YueHaibing 0977763a13 appletalk: Fix potential NULL pointer dereference in unregister_snap_client ...

commit 9804501fa1 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
