v4l2: v4l2_camera_proxy: Zero flags in VIDIOC_REQBUFS
The V4L2 compatibility layer doesn't support any of the VIDIOC_REQBUFS
flags. They are all correctly ignored, but also need to be zeroed
before returning to indicate that they haven't been taken into account.
This fixes a v4l2-compliance failure:
Buffer ioctls (Input 0):
fail: ../../utils/v4l2-compliance/v4l2-test-buffers.cpp(682): coherent
test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: FAIL
Fixes: aa4533639971 ("include: linux: Update kernel headers to version v5.16-rc7")
