As shown in GH #2550, Coverity is tempted to think that NULL-dereference can occur in _lf_cbor_encode_byte() due to user-ctx being dereferenced from cbor_ctx, while coverity thinks that cbor_ctx may be NULL. In practise this cannot happen, because _lf_cbor_encode_byte() is only leveraged through a function pointer that is set in conjunction with the function pointer ctx (which ain't NULL). All this logic is done inside lf_buildctx_prepare() when LOG_OPT_ENCODE_CBOR is set. Since coverity doesn't seem to understand the logic properly, then it might as well confuse humans, so let's make it clear in _lf_cbor_encode_byte() that we expect non-NULL ctx by adding a BUG_ON()
