On hotplug case, after a pdev is removed from the system, edev->mode will
set flag EEH_DEV_NO_HANDLER to mark the status. While this flag is not
cleared when we probe back those pdev. This will lead to miss the call of
driver->err_handler->slot_reset in eeh_report_reset().
This patch clear this flag when probe back those devices.
