Subject: [PATCH v18 9/9] media: verisilicon: Support deleting buffers on capture queue

Allow to delete buffers on capture queue because it the one which
own the decoded buffers. After a dynamic resolution change lot of
them could remain allocated but won't be used anymore so deleting
them save memory.
