[SCSI] libfc: change debug messages to give host number.
libfc debug messages currently show 'lport: <fc-id>:'
wher <fc-id> is the hex assigned port-id. When the lport
is logged off, that will be zero, so its hard to distinguish
which instance is involved. The FC-ID can change
if the port is re-patched or changes VSANs.
Two lports may even have the same FC-ID if connected to isolated SANs.
Change the debug messages to print the SCSI host number "hostN:",
which will not change for the life of the lport.
Still show the FC_ID on lport messages.
Also, add a macro to FC_RPORT_ID_DBG for rport debugging where there's
no rdata structure involved. It takes the lport and port_id as parameters.
Use this in fc_rport_recv_plogi_req() and fc_rport_recv_logo_req().
