cam: capture: Stop stream when queueRequest() fails

Browse source 
queueRequest() is called after starting the stream.
If it fails, the stream should be stopped, otherwise it can get a
"Device or resource busy" error, due to VIDIOC_REQBUFS ioctls being
called after VIDIOC_STREAMON without VIDIOC_STREAMOFF in-between.
