V4L/DVB (11277): tvaudio: always call init_timer to prevent rmmod crash.
In the tvaudio_remove function del_timer_sync(&chip->wt) is called.
However, chip->wt isn't always initialized depending on the type of
audio chip. Since del_timer_sync hangs when given an uninitialized timer
we should always initialize it.
