In my game I did steal Nito's soul early (before waking him with the bells), Ciaran showed up and I got the message that she took it back (though it didn't disappear from my inventory.) Shortly after I started Velka's quest. I've maintained Velka's quest so far, done the intended DLC progression, and Ciaran was in fact waiting there for me to receive Artorias's soul. So attempting to steal a sleeping Nito's soul does not break Ciaran's (and thus Velka's) quest, at least if you do things in that order.
