lpfc: Fix default RA_TOV and ED_TOV in the FC/FCoE driver for all topologies

Submitted by james.smart () james.smart.()@emulex.com

Fix default RA_TOV and ED_TOV in the FC/FCoE driver for all topologies

Initial link up defaults were not properly being tracked relative to
initial FLOGI or pt2pt PLOGI. Add code to initialize them.
