The 'channel' argument of hif_join() should never be NULL. hif_join()
does not have the responsibility to recover bug of caller.

In current code, if the argument channel is NULL, memory leaks. The new
code just emit a warning and does not give the illusion that it is
supported (and indeed a Oops will probably raise a few lines below).
