Hans de Goede bceff719ef media: atomisp: Avoid deadlock with sensor subdevs with state_lock set 
When a (sensor) v4l2_subdev has its state_lock member set to non NULL,
then all v4l2_subdev_state-s for the sensor share the same lock.

atomisp_init_sensor() calls v4l2_subdev_lock_and_get_active_state() and
then later on also tries to lock a separate v4l2_subdev_state used for try
calls (rather then changing the active state), while still holding
the active state lock.

Since this try v4l2_subdev_state shares a lock with the active state this
results in a deadlock.

Skip locking try_sd_state when sensor->state_lock is set to avoid this.
