[XFS] Remove vn_revalidate calls in xfs.
These days most of the attributes in struct inode are properly kept in sync by XFS. This patch removes the need for vn_revalidate completely by: - keeping inode.i_flags uptodate after any flags are updated in xfs_ioctl_setattr - keeping i_mode, i_uid and i_gid uptodate in xfs_setattr SGI-PV: 984566 SGI-Modid: xfs-linux-melb:xfs-kern:31679a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Tim Shimmin <tes@sgi.com> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
