xfs: update lazy sb counters immediately for resizefs
sb_fdblocks will be updated lazily if lazysbcount is enabled, therefore when shrinking the filesystem sb_fdblocks could be larger than sb_dblocks and xfs_validate_sb_write() would fail. Even for growfs case, it'd be better to update lazy sb counters immediately to reflect the real sb counters. Reviewed-by: Darrick J.
