libmultipath: add condition for enqueueing path to io error check

In function io_err_stat_handle_pathfail(), path->io_err_dis_reinstate_time
is set to 0 to enqueue path to io error check as soon as possible. But
multipathd can not do it within marginal_path_err_recheck_gap_time seconds
after power-on, because curr_time is less than
marginal_path_err_recheck_gap_time.

To handle the early marginal path, we can enqueue path when
io_err_dis_reinstate_time is 0.
