media: ov2680: Don't take the lock for try_fmt calls
On ov2680_set_fmt() calls with format->which == V4L2_SUBDEV_FORMAT_TRY,
ov2680_set_fmt() does not talk to the sensor.
So in this case there is no need to lock the sensor->lock mutex or
to check that the sensor is streaming.
Fixes: 3ee47cad3e69 ("media: ov2680: Add Omnivision OV2680 sensor driver")
