sfc: Store the efx_nic struct of the current VF in the VF data struct
Initialised in efx_probe_vf and removal is dealt with in
efx_ef10_remove.
vf->efx is needed in future patches to change the MAC address
of the VF via the parent PF, while the driver is bound to the
VF.
Example: ip link set dev vf NUM mac LLADDR
