But in i40e_asq_send_command, it will return I40E_ERR_ADMIN_QUEUE_ERROR if the return value of Admin Queue command processed by Firmware is not I40E_AQ_RC_OK or I40E_AQ_RC_EBUSY. Use i40e_aq_remove_macvlan_v2 instead so that we can get the corresponding Admin Queue status, and not report as an error in DPDK when Firmware return I40E_AQ_RC_ENOENT.
