Avoid calling RtpFrameObject::GetCodecHeader twice in the RtpFrameReferenceFinder.

This is good for a few reasons:
 - We avoid grabing a lock twice.
 - We avoid an unnecessary copy.
 - We avoid a race where a packet could potentially be removed before the
   second time we call GetCodecHeader.

BUG=None
