dvr_read_buffer_queue: don't stop releasing buffer

We used to abort ReleaseBuffer logic if we cannot verify that the buffer
being released is in the target queue. However, in certain edge case,
this could be true and we still want to release the buffer. One example
is when a ProducerQueue closes and triggers its ConsumerQueue to remove
all its buffers. In this case, ConsumerQueue::ReleaseBuffer() should
still function properly.
