[SCSI] fnic: Allow multicast and unicast address registrations for fnic

To enable FIP support in fnic, we have to register with hardware to receive
FIP solication frames on a well-known multicast address.
Before FIP support, the firmware interface allowed multicast address
registrations only for enic devices. This is a minor change in fnic to
allow the firmware interface to now register mcast addresses for fnic too.
