Char: cyclades, fix potential NULL dereference
ztxdone is jumped to even if tty is NULL and tty_wakeup placed after
this label doesn't expect NULLed parameter, so this will cause an oops
in some situations (why they scheduled a wakeup there before remove
bottom half processing patch?).
wakeup only in the case when we have non-null tty struct.
