[GFS2] remove unnecessary permission checks
Remove read/write permission() checks from xattr operations. VFS layer is already handling permission for xattrs via the xattr_permission() call, so there is no need for gfs2 to check permissions. Futhermore, using permission() for SELinux xattrs ops is incorrect. Signed-off-by: Ryan O'Hara <rohara@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
