These functions tried to check the state of the buffer's content lock even for local buffers. Since we don't use the content lock for a local buffer, that would lead to a "false" result from LWLockHeldByMeInMode, which would mean a misleading "false" answer from BufferIsExclusiveLocked (we'd rather that case always return "true") or an assertion failure in BufferIsDirty. The core code never applies these two functions to local buffers, and apparently no extensions do either, since we've not heard complaints. Still, in the name of future-proofing, let's fix them to act as though a pinned local buffer is content-locked.
