net/queue: queue packets even if sender doesn't supply a callback

Browse Source 
Now that we disable any receiver whose queue is full, we do not require
senders to handle a zero return by supplying a sent callback.

This is a second step towards allowing can_receive() handlers to return
true even if no buffer space is available.
