ffmpeg | branch: master | Devin Heitmueller <devin.heitmueller at ltnglobal.com> | Fri Mar 17 11:02:31 2023 -0400| [85c62b48e9189d84746009f26a4cff41ad5d4603] | committer: Marton Balint

avcodec/bytestream: fix warnings with signed/unsigned compare in bytestream.h

When including the header in decklink_enc.cpp it would be fed
through the C++ compiler rather than the C compiler, which has
more strict warnings when comparing signed/unsigned values.

Make the local variables unsigned to match the arguments they are
being passed for those functions.
