[SCSI] qla2xxx: Access the proper 'physical' port in FC-transport callbacks.

 For following fc_host specific attributes, vports rely on the pport.
 So, this patch changed way to access the data for those attributes so that
 they can access pport's.
 - get_host_speed (speed)
 - get_host_port_state (port_state)
 - get_host_port_type (port_type)
 - get_fc_host_stats

Also, added PORT_SPEED_8GB case in the speed attribute for 8Gb HBAs.
