media: i2c: imx219: Fix crop rectangle setting when changing format

When moving the imx219 driver to the subdev active state, commit
e8a5b1df000e ("media: i2c: imx219: Use subdev active state") used the
pad crop rectangle stored in the subdev state to report the crop
rectangle of the active mode. That crop rectangle was however not set in
the state when setting the format, which resulted in reporting an
incorrect crop rectangle to userspace. Fix it.
