vdpa: Use iovec for vhost_vdpa_net_load_cmd()
According to VirtIO standard, "The driver MUST follow
the VIRTIO_NET_CTRL_MAC_TABLE_SET command by a le32 number,
followed by that number of non-multicast MAC addresses,
followed by another le32 number, followed by that number
of multicast addresses."
Considering that these data is not stored in contiguous memory,
this patch refactors vhost_vdpa_net_load_cmd() to accept
scattered data, eliminating the need for an addtional data copy or
packing the data into s->cvq_cmd_out_buffer outside of
vhost_vdpa_net_load_cmd().
