mvsas: fix local port name regression

Commit a692b0e "[SCSI] libsas: fix sas port naming" added a dependency
on lldds filling out the id field of registered phys.  Add this for
mvsas.

Note we do this in the lldd rather than the core to allow it the control
of mappping physical phy id to the libsas phy index.
