Increase VIDIOC_REQBUFS count from 2 to 4
The original config of 2 buffers is too few. The kernel may be throttled with no
buffer to queue when Chrome doesn't return the buffer in time. Reserve two more
buffers gives Chrome extra 60ms to process incoming frame on a 30fps camera.

TEST=Check 'uvcvideo: Dropping payload' messages in kernel logs
