So all resources previously released in remove routine are now released at the dev_close routine, and the dev_close routine will be called in driver remove routine in order to support removing a device without closing its ports. Above behavior changes are supported by setting RTE_ETH_DEV_CLOSE_REMOVE flag during probe stage.
