[dm-devel] [PATCH] libmultipath: ensure dev_loss_tmo will be update to MAX_DEV_LOSS_TMO if no_path_retry set to queue

[peng.liang5 at zte.com.cn]

From: PengLiang <peng.liang5 at zte.com.cn>

If no_path_retry set to queue, we should make sure dev_loss_tmo update to MAX_DEV_LOSS_TMO.
But, it will be limit to 600 if fast_io_fail_tmo set to off or 0 meanwhile.
