Subject: [PATCH] Fix set_no_path_retry() regression
commit 0f850db7fceb6b2bf4968f3831efd250c17c6138 "multipathd: clean up
set_no_path_retry" has a bug in it. It made set_no_path_retry
never reset mpp->retry_ticks, even if the device was in recovery mode,
and there were valid paths. This meant that adding new paths didn't
remove a device from recovery mode, and queueing could get disabled,
even while there were valid paths. This patch fixes that.
This patch also fixes a bug in cli_restore_queueing() and
cli_restore_all_queueing(), where a device that had no_path_retry
set to "queue" would enter recovery mode (although queueing would
never actually get disabled).
