Fix error BufferQueue attaching flow.

Fix error BufferQueue attaching flow. Because BufferQueue attaching
buffer flow doesn't set mNeedsReallocation to false, it will case
Surface client to request buffer for attached buffer to cause unsync
buffer states with ACodec. So, for attaching buffer by Producer, we
need to set mNeedsReallocation to false in BufferQueue. And Surface
client will not request buffer again for attached buffer to cause
some missing frames.
