media: atomisp: Remove v4l2_ctrl_s_ctrl(asd->run_mode) calls from atomisp_open()

The v4l2_ctrl_s_ctrl(asd->run_mode) call in atomisp_subdev_init_struct()
gets immediately overridden by a second call directly after
atomisp_subdev_init_struct() is called.

And the second call in atomisp_open() also is not helpful.
ATOMISP_RUN_MODE_PREVIEW is the default and if changed controls
are supposed to stay changed over an open/close of the /dev/video#
node. So drop both calls.
