[SCSI] libfc fcoe: increase ELS and CT timeouts
The FC-LS spec. says ELS timeouts should be 2 x R_A_TOV. The FC-GS spec. says CT timeouts should be 3 x R_A_TOV. We've been using E_D_TOV for both of those. Change for all ELS and CT requests except FLOGI, which we leave at 2 seconds (using E_D_TOV). One could argue that R_A_TOV is locally determined until after FLOGI succeeds. This does change FLOGI for vports which becomes FDISC. This does not change the REC/SRR timeout which is 2 seconds.
