pds_vdpa: always allow offering VIRTIO_NET_F_MAC
Our driver sets a mac if the HW is 00:..:00 so we need to be sure to
advertise VIRTIO_NET_F_MAC even if the HW doesn't. We also need to be
sure that virtio_net sees the VIRTIO_NET_F_MAC and doesn't rewrite the
mac address that a user may have set with the vdpa utility.
After reading the hw_feature bits, add the VIRTIO_NET_F_MAC to the driver's
supported_features and use that for reporting what is available. If the
HW is not advertising it, be sure to strip the VIRTIO_NET_F_MAC before
finishing the feature negotiation. If the user specifies a device_features
bitpattern in the vdpa utility without the VIRTIO_NET_F_MAC set, then
don't set the mac.
