[media] DVB: dvb_frontend: update locking in dvb_frontend_{add, get_event}
- fepriv->parameters_out isn't protected by events->mtx, so
move the call to fe->ops.get_frontend out of the locked area.
- move the assignment of e->status into the locked area.
- use direct assignment instead of memcpy.
- use mutex_lock instead of mutex_lock_interruptible, because
all code paths protected by this mutex won't block.
