xfs: add selinux labels to whiteout inodes
We got a report that "renameat2() with flags=RENAME_WHITEOUT doesn't
apply an SELinux label on xfs" as it does on other filesystems
(for example, ext4 and tmpfs.) While I'm not quite sure how labels
may interact w/ whiteout files, leaving them as unlabeled seems
inconsistent at best. Now that xfs_init_security is not static,
rename it to xfs_inode_init_security per dchinner's suggestion.
