media: atomisp: Simplify atomisp_subdev_set_selection() calls in atomisp_set_fmt()

With the atomisp_subdev_set_selection(sink-pad, V4L2_SEL_TGT_CROP, rect)
calls dropped. The first and last compount code blocks of the 3 code blocks
in the if (...) {} else if (...) {} else {} code setting the source-pad
V4L2_SEL_TGT_COMPOSE selection are the same.

The both set V4L2_SEL_TGT_COMPOSE to a rectangle with the same dimensions
as f->fmt.pix.height.

Remove the else {} block at the end, drop the second if and prepend
the first if condition with "!second-if-condition ||" to remove
the code duplication.
