scsi: lpfc: Change VMID registration to be based on fabric parameters
Currently, VMID registration is configured via module parameters. This
could lead to VMID compatibility issues if two ports are connected to
different brands of switches, as the two brands implement VMID differently.
Make logical changes so that VMID registration is based on common service
parameters from FLOGI_ACC with fabric rather than module parameters.
