media: atomisp: Remove redundant atomisp_subdev_set_selection() calls from atomisp_set_fmt()

atomisp_subdev_set_selection(sink-pad, V4L2_SEL_TGT_CROP, rect)
ignores the passed in rect, using the width and height from the last
atomisp_subdev_set_ffmt(ATOMISP_SUBDEV_PAD_SINK, ffmt) call instead.

The atomisp_subdev_set_ffmt() call done by atomisp_set_fmt_to_snr()
already propagates the sink ffmt changes to V4L2_SEL_TGT_CROP
(this is what allows atomisp_set_fmt() to get the isp_sink_crop in
the first place).

Remove the redundant atomisp_subdev_set_selection(sink-pad, ...)
calls.

Note the removed aspect ratio correction in the last else block is
is already done by atomisp_subdev_set_selection() itself when
setting V4L2_SEL_TGT_COMPOSE on the source-pad.
