ext4: check if in-inode xattr is corrupted in ext4_expand_extra_isize_ea()
commit 9e92f48c34eb2b9af9d12f892e2fe1fce5e8ce35 upstream.
We aren't checking to see if the in-inode extended attribute is
corrupted before we try to expand the inode's extra isize fields.
This can lead to potential crashes caused by the BUG_ON() check in
ext4_xattr_shift_entries().
