media: i2c: imx219: Access height from active format in imx219_set_ctrl

Use the active format height instead of the mode height in
imx219_set_ctrl(). This prepares for dropping the mode field from the
imx219 structure.

The state is retrieved using v4l2_subdev_get_locked_active_state() as
the subdev active state and the control handler share the same lock.
