[SCSI] libfc: change elsct to use FC_ID instead of rdata
tt.elsct_send is used by both FCP and by the rport state machine. After further patches, these two modules will use different structures for the remote port. So, change elsct_send to use the FC_ID instead of the fc_rport_priv as its argument. It currently only uses the FC_ID anyway. For CT requests the destination FC_ID is still implicitly 0xfffffc. After further patches the did arg on CT requests will be used to specify the FC_ID being inquired about for GPN_ID or other queries.
