rlcmac: Fix Last RLC block (CV=0) not encoding >1 LLC frames
Before this patch, the last RLC block (CV=0) would only be filled with up to 1 LLC frame, even if several LLC frames were enqueued and expected to be put in that RLC frame (CV calculation). Fixes the unit test provided in an earlier patch.
