Even though no_path_retry is set for time based queuing(i.e no_path_retry <N>), I/O is getting queued for ever. During all path failure condition, setup_feature() resets no_path_retry of multipath structure to NO_PATH_RETRY_QUEUE which queues I/O for ever. This patch skips resetting no_path_retry until no_path_retry is set with queue.
