[SCSI] libfc: make rport structure optional
Allow a struct fc_rport_priv to have no fc_rport associated with it. This sets up to remove the need for "rogue" rports. Add a few fields to fc_rport_priv that are needed before the fc_rport is created. These are the ids, maxframe_size, classes, and rport pointer. Remove the macro PRIV_TO_RPORT(). Just use rdata->rport where appropriate. To take the place of the get_device()/put_device ops that were used to hold both the rport and rdata, add a reference count to rdata structures using kref. When kref_get decrements the refcount to zero, a new template function releasing the rdata should be called. This will take care of freeing the rdata and releasing the hold on the rport (for now). After subsequent patches make the rport truly optional, this release function will simply free the rdata. Remove the simple inline function fc_rport_set_name(), which becomes semanticly ambiguous otherwise. The caller will set the port_name and node_name in the rdata->Ids, which will later be copied to the rport when it its created.
