vo: don't synchronize when seeking

Don't use vo_control() for sending VOCTRL_RESET when starting a seek.
This means vo_seek_reset() won't wait until the VO actually processed
VOCTRL_RESET. It happens asynchronously instead.

The impact of this change should be minimal, unless the VO is somehow
too busy (like blocking on vsync).
