IRC_KillClient(): Don't break when called without "Client"
The IRC_KillClient() function is documented to handle the case that the
"Client" structure is NULL, so make sure that this actually works and
can't crash the daemon.
Please note:
The current code doesn't make use of this feature, so this fix is
definitely the "right" thing to do but doesn't fix an actual problem.
