Johan Hovold 11d4d32158 tty: ehv_bytechan: clean up init error handling ...

Straighten out the initcall error handling to avoid deregistering a
never-registered tty driver (something which would lead to a
NULL-pointer dereference) in the most unlikely event that driver
registration fails (e.g. we've run out of major numbers).
