Subject: [PATCH 09/15] media: blackfin: bfin_capture: make sure all buffers are returned on stop_streaming() callback

In start_streaming() callback the buffer is removed from the
dma_queue list and assigned to cur_frm, this patch makes sure
that is returned to vb2 core with VB2_BUF_STATE_ERROR flag.
