syncop: fix conditional wait bug in parallel dir scan
Problem: The issue as seen by the user is detailed in the BZ but what is happening is if the no. of items in the wait queue == max-qlen, syncop_mt_dir_scan() does a pthread_cond_wait until the launched synctask workers dequeue the queue. But if for some reason the worker fails, the queue is never emptied due to which further invocations of syncop_mt_dir_scan() are blocked forever. Fix: Made some changes to _dir_scan_job_fn - If a worker encounters error while processing an entry, notify the readdir loop in syncop_mt_dir_scan() of the error but continue to process other entries in the queue, decrementing the qlen as and when we dequeue elements, and ending only when the queue is empty. - If the readdir loop in syncop_mt_dir_scan() gets an error form the worker, stop the readdir+queueing of further entries.
