Intel iavf: Return in the case of ADD/DEL ETH address
In case of i40vf, VIRTCHNL_OP_DEL_ETH_ADDR and VIRTCHNL_OP_ADD_ETH_ADDR are unsupported.
i40evf_execute_vf_cmd is invoked with these operations as part of i40evf_set_mc_addr_list()
The cases are not handled in i40evf_execute_vf_cmd() thus hitting the default case.
There is a retry logic of upto 200 times (2000 in iavf) with a delay of 10ms (1ms in iavf).
This results in a needless delay of 2s in the init phase for each VNIC.
The patch aims to rectify that delay.
In fe2a571c70cc397f2ad4e280f8d084148fea5d62, i40e_ethdev_vf.c was deleted. Hence adding this in iavf_vchnl.c.

Hi, this is problem was discovered while using i40vf (which was deprecated and replaced by iavf).
