[media] vb2: V4L2_BUF_FLAG_DONE is set after DQBUF
According to the doc, V4L2_BUF_FLAG_DONE is cleared after DQBUF:
V4L2_BUF_FLAG_DONE 0x00000004 ... After calling the VIDIOC_QBUF or
VIDIOC_DQBUF it is always cleared ...
Unfortunately, it seems that videobuf2 keeps it set after DQBUF. This
can be tested with vivid and dev_debug:
[257604.338082] video1: VIDIOC_DQBUF: 71:33:25.00260479 index=3,
type=vid-cap, flags=0x00002004, field=none, sequence=163,
memory=userptr, bytesused=460800, offset/userptr=0x344b000,
length=460800
This patch forces FLAG_DONE to 0 after calling DQBUF.
