It's a normal process. When liverocks are transferred to a new setup, you will expect to see a lot of die offs as many little creatures like worms, crabs snails etc etc cannot adapt to the new enviroment. The water will sure to stink but don't worry, it will go away in a couple of days, trust me. Just continue to let your tank go through the cycling process, it might be anytime from 4-6 weeks and if you can wait longer will be much better. So just sit back and relax, no need to remove the rocks or change any water.
Before adding any live stock, please check the water parameters like ammonia, NO2, PH etc etc to see whether your tank is fully cycled or not. Mine is also going through cycling process right now and the smell had gone away just after 2 days. So good luck and hoped to see an update of ur setup soon!
