libglusterfs/syncop: do not rely on synctask set in makecontext
Across glibc implementations, interpretation of argc/argv passed to makecontext() is different. This patch does away with dependence on such arguments passed to makecontext(). Instead,synctask reference is retrieved from pthread_getspecific().
