uvcvideo: Remove buffers from the queues when freeing
commit 8ca2c80b170c47eeb55f0c2a0f2b8edf85f35d49 upstream.
When freeing memory for the video buffers also remove them from the
irq & main queues.
This fixes an oops when doing the following:
open ("/dev/video", ..)
VIDIOC_REQBUFS
VIDIOC_QBUF
VIDIOC_REQBUFS
close ()
As the second VIDIOC_REQBUFS will cause the list entries of the buffers
to be cleared while they still hang around on the main and irc queues
