If ctrlr_loss_timeout_sec is set to -1, reconnect is tried repeatedly indefinitely, and I/Os continue to be queued. This patch adds another option fast_io_fail_timeout_sec, a flag fast_io_fail_timedout to nvme_ctrlr. If the time fast_io_fail_timeout_sec passed after starting reset, set fast_io_fail_timedout to true not to use the path for I/O submission. fast_io_fail_timeout_sec is initialized to zero as same as ctrlr_loss_timeout_sec and reconnect_delay_sec. The name of the parameter follows the famous DM-multipath, its fast_io_fail_tmo.
