[Guardians of the Galaxy] What if Ronan gave Thanos the Power Stone instead of keeping it?

Title. What if he just handed it to him. Granted, at this time, I don't believe Thanos had the Infinity Guantlet. So what happens next in the grand scheme of things?

The same events would probably play out. He would still wait for ego, sourcerer supreme, and odin to die before he continued on with his plans like what he did in the normal sequence of events. 

If he were to start collecting the stones sooner in your scenario, one of the 3 aforementioned characters might have caught on. Knowing this, he would still wait for odin to pass and therefore asguard to be destroyed and he would attack the asguardian ship as usual.
