On the following call path:
gfs2_setattr -> setattr_prepare -> ... ->
cap_inode_killpriv -> ... ->
gfs2_xattr_set
the glock is locked in gfs2_setattr, so check for recursive locking in
gfs2_xattr_set as gfs2_xattr_get already does. While at it, get rid of
need_unlock in gfs2_xattr_get.
Fixes xfstest generic/093.
