appletalk: Fix potential NULL pointer dereference in unregister_snap_client
commit 9804501fa1228048857910a6bf23e085aade37cc upstream.
register_snap_client may return NULL, all the callers
check it, but only print a warning. This will result in
NULL pointer dereference in unregister_snap_client and other
places.
It has always been used like this since v2.6
