media: atomisp: Fix VIDIOC_TRY_FMT
atomisp_try_fmt() calls the sensor's try_fmt handler but it does not copy the result back to the passed in v4l2_pix_format under some circumstances. Potentially returning an unsupported resolution to userspace, which VIDIOC_TRY_FMT is not supposed to do. atomisp_set_fmt() also uses atomisp_try_fmt() and relies on this wrong behavior. The VIDIOC_TRY_FMT call passes NULL for the res_overflow argument where as the atomisp_set_fmt() call passes non NULL. Use the res_overflow argument to differentiate between the 2 callers and always propagate the sensors result in the VIDIOC_TRY_FMT case. This fixes the resolution list in camorama showing resolutions like e.g. 1584x1184 instead of 1600x1200.
