Firmware will return I40E_AQ_RC_ENOENT when try to delete non-existent
MAC/VLAN addresses from the HW filtering, this should not be considered as
an Admin Queue error. 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.

Fixes: 4861cde46116 ("i40e: new poll mode driver")
