xfs_check_ondisk_structs() verifies that the sizes of the data types
used by xfs are correct via the XFS_CHECK_STRUCT_SIZE() macro.
xfs_dir2_sf_entry_t size is set erroneously to 3 which breaks the
compilation with the assertion below:
In file included from linux/include/linux/string.h:6,
from linux/include/linux/uuid.h:12,
from linux/fs/xfs/xfs_linux.h:10,
from linux/fs/xfs/xfs.h:22,
from linux/fs/xfs/xfs_super.c:7:

inlined from ‘init_xfs_fs’ at linux/fs/xfs/xfs_super.c:2025:2:
linux/include/linux/compiler.h:350:38:
error: call to ‘__compiletime_assert_107’ declared with attribute
error: XFS: sizeof(xfs_dir2_sf_entry_t) is wrong, expected 3
_compiletime_assert(condition, msg, __compiletime_assert_, __LINE__)
Restore the correct behavior defining the correct size.
