adhoc: fix bogus Failed error and segfault on stop

The netdev_leave_adhoc() returns a negative errno on errors and zero
on success, but adhoc_dbus_stop() assumed the inverse when checking for
an error.

Also, the DBus message was not being referenced in adhoc->pending and
then adhoc_leave_cb() segfaulted attempting to dereference it.
