media: msp3400: Use wait_event_freezable_timeout() in msp_sleep()

Browse source

The msp_sleep() is nearly open-coded wait_event_interruptible_timeout(),
and a freezable kernel thread can enter frozen state during freezing by
either calling try_to_freeze() or using wait_event_freezable() and its
variants. So we can reimplement msp_sleep() to simply invoke
a wait_event_freezable_timeout() and then eliminate a call to
try_to_freeze().
