[media] solo6x10: release vb2 buffers in solo_stop_streaming()
Fixes warning that appears in dmesg after closing V4L2 userspace
application that plays video from the display device
(first device from V4L2 device nodes provided by solo, usually /dev/video0
when no other V4L2 devices are present). Encoder device nodes are not
affected. Can be reproduced by starting and closing
ffplay -f video4linux2 /dev/video0
