staging: i4l: pcbit: drv: use setup_timer() and mod_timer().
Use setup_timer() instead of init_timer(), being the preferred/standard
way to set a timer up.
Also, quoting the mod_timer() function comment:
-> mod_timer() is a more efficient way to update the expire field of an
active timer (if the timer is inactive it will be activated).
Use setup_timer and mod_timer to setup and arm a timer, to make the code
cleaner and easier to read.
