gfapi: Unblock epoll thread for upcall processing

With commit#ad35193,we have made changes to offload
processing upcall notifications to synctask so as not
to block epoll threads. However seems like the issue wasnt
fully addressed.

In "glfs_cbk_upcall_data" -> "synctask_new1" after creating synctask
if there is no callback defined, the thread waits on synctask_join
till the syncfn is finished. So that way even with those changes,
epoll threads are blocked till the upcalls are processed.

Hence the right fix now is to define a callback function for that
synctask "glfs_cbk_upcall_syncop" so as to unblock epoll/notify threads
completely and the upcall processing can happen in parallel by synctask
threads.
