[SCSI] fc_transport: Add an API to allow an LLD to create vports
There's already a fc_vport_termintate() call exported by
the transport. This patch adds a symmetric call to the API to allow
an NPIV-capable LLD to instantiate vports sans user intervention.
Additional comments/updates:
Re: scsi_fc_transport.txt
Add a function prototype for fc_vport_terminate similar to what's
done for fc_vport_create
Re: fc_vport_create
I recommend we pass the channel number in fc_vport_create rather
than fixing it at zero.
Also, ids->vport_type should be set to FC_PORTTYPE_NPIV prior to
calling fc_vport_create. The comment is also meaningless.
