After going back and rereading that fight, it seems your right. His sword is in shikai form. However he still doesn't know the name of his sword, so they aren't cooperating together, which limits it 'true' strength greatly as said here
Also by rereading that fight, I figured out what that image Zaraki saw of himself being stabbed was. It's the killing intent of Unohana completely overwhelming him. He did that same shit to Ichigo himself way back when they first met.
LOL, at those great memories. This basically proves Unohana is toying with Zaraki pretty bad if she can mind fuck him to this degree.
Edit: I wonder how Zaraki ever unlocked his shikai to begin with though? Even if he's the same as Ichigo to where it's stays in shikai form, if you remember ichigo still had to learn Zangetsus' name to unlock it to begin with. How does one unlock a sword with no name, when learning the name has always been shown to be the the requirement? Some sort of SS experiment?
