cluster/dht: Make sure gf_defrag_migrate_data is not optimized
Problem: Whenever there syncop_xxx() is used inside a synctask and gcc optimizes it when compiled with -O2 there is a problem where 'errno' would not work as expected. Fix: Until http://review.gluster.com/6475 is reviewed and merged we are making sure the function is not going to be optimized.
