From: Jérôme Pouiller <jerome.pouil...@silabs.com>
The 'channel' argument of hif_join() should never be NULL. hif_join()
does not have the responsibility to recover bug of caller. A call to
WARN() at the beginning of the function reminds this constraint to the
developer.
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).
