Cleanup remove_channel()

Browse Source 
remove_channel() is only called in direct response to a message from a server,
so it always acts on from_server - remove the unnecessary server argument.

The channel argument is always non-NULL - remove the dead code that removed all
channels if a NULL channel was passed.
