TAKE 984566 - kill vn_revalidate - set inode fields in setattr explicitly

[tes@xxxxxxx (Tim Shimmin)]

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
