Add braces around variables used within macros for those make sense
to do it. Many of the macros in f2fs already do this. What this commit
doesn't do is anything that changes line# as a result of adding braces,
which usually affects the binary via __LINE__.
Confirmed no diff in fs/f2fs/f2fs.ko before/after this commit on x86_64,
to make sure this has no functional change as well as there's been no
unexpected side effect due to callers' arithmetics within the existing
code.

In this patch, we change xattr block disk layout as below:
Before:
xattr node block layout
+---------------------------------------------+---------------+-------------+
| node block xattr entries | reserved | node footer |
| 4068 Bytes | 4 Bytes | 24 Bytes |
In memory layout
+--------------------+---------------------------------+--------------------+
| inline xattr | node block xattr entries | reserved |
| 200 Bytes | 4068 Bytes | 4 Bytes |
After:
xattr node block layout
+-------------------------------------------------------------+-------------+
| node block xattr entries | node footer |
| 4072 Bytes | 24 Bytes |
In memory layout
+--------------------+---------------------------------+--------------------+
| inline xattr | node block xattr entries | reserved |
| 200 Bytes | 4072 Bytes | 4 Bytes |
With this change, we don't need to reserve additional space in node block,
just keep reserved space in logical in-memory layout. So that it would help
to enlarge valid free space of xattr node block.
As tested, generic/026 shows max stored xattr entires number increases from
531 to 532 when inline_xattr option is enabled.

1. don't allocate redundant memory in read_all_xattrs.
2. introduce RESERVED_XATTR_SIZE for cleanup.

Previously, in getxattr we will load all entries both in inline xattr and
xattr node block, and then do the lookup in all entries, but our lookup
flow shows low efficiency, since if we can lookup and hit in inline xattr
of inode page cache first, we don't need to load and lookup xattr node
block, which can obviously save cpu time and IO latency.

The f2fs_setxattr() prototype for CONFIG_F2FS_FS_XATTR=n has
been wrong for a long time, since 8ae8f1627f39 ("f2fs: support
xattr security labels"), but there have never been any callers,
so it did not matter.
Now, the function gets called from f2fs_ioc_keyctl(), which
causes a build failure:
fs/f2fs/file.c: In function 'f2fs_ioc_keyctl':
include/linux/stddef.h:7:14: error: passing argument 6 of 'f2fs_setxattr' makes integer from pointer without a cast [-Werror=int-conversion]

Thsi changes the prototype of the empty stub function to match
that of the actual implementation. This will not make the key
management work when F2FS_FS_XATTR is disabled, but it gets it
to build at least.

f2fs: fix to skip shrinking extent nodes
In f2fs_shrink_extent_tree we should stop shrink flow if we have already
shrunk enough nodes in extent cache.
