media: atomisp: Remove bogus fh use from atomisp_set_fmt*()

Browse source

atomisp_set_fmt*() use a local v4l2_subdev_fh declared on the stack,
specifically they use fh.state which is never initialized so when
passing fh.state to atomisp_subdev_set_ffmt() / to
atomisp_subdev_set_selection() these functions are passing random
stack contents as a pointer.

The reason this works is because when the which parameter is
V4L2_SUBDEV_FORMAT_ACTIVE the passed in state is not used.

Remove the bogus fh usage and just pass NULL as state.
