[SCSI] libfc: use PRLI hook to get parameters when sending outgoing PRLI

Browse Source 
When sending an outgoing PRLI as an initiator, get the parameters
from registered providers so that they all get a chance to decide
on roles.

The passive provider is called last, and could override the
initiator role.
