f2fs: fix i_current_depth during inline dentry conversion
With below steps, we will see that dentry page becoming unaccessable later.
This is because we forget updating i_current_depth in inode during inline
dentry conversion, after that, once we failed at somewhere, it will leave
i_current_depth as 0 in non-inline directory. Then, during ->lookup, the
current_depth value makes all dentry pages in first level invisible. Fix
it.
1) mount f2fs with inline_dentry option
2) mkdir dir
3) touch 180 files named [0-179] in dir
4) touch 180 in dir (fail after inline dir conversion)
5) ll dir
