[SCSI] fc_transport: update potential link speeds

This patch updates the FC transport for all speeds identified in
SM-HBA.  Note: it does not sync the "bit" definitions, as that is
actually insulated from user-space via the sysfs text string. (I could
do it, but it does introduce a potential binary-incompatibility).
