tty: Power: fix suspend vt regression 

vt_waitactive no longer accepts console parameter as console-1
since commit "vt: add an event interface". It expects console
number directly (as viewed by userspace -- counting from 1).

Fix a deadlock suspend regression by redefining adding one
to vt in vt_move_to_console.
