libglusterfs/syncop: do not rely on synctask set in makecontext

Browse Source 
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().
