[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.
