Uncouncious would mean that he was KOed after receiving an atack and couldnt wake up at all, wich is not true at all, he slept only after he left the fight and wake up just to give orrderrs to Sanji when he was carrying him.
luffy gets partially hit by a TB and survives but a TB to the face knocks him out
you see the difference.. zoro got himself flipped over by TB and the attack was focused on Law who tanked it like pro
sleeping = unconscious... and keeps getting unconscious.. thats the point what there to cry about?
