V4L/DVB (9031): uvcvideo: Fix incomplete frame drop when switching to a variable size format.
When streaming in a fixed size format the driver sets a flag in the uvc_queue
structure to drop incomplete incoming frames. The flag wasn't cleared when
switching to a variable size format, which resulted in a broken
'MJPEG after YUV'.
