ionic: replay VF attributes after fw crash recovery

Browse Source 
The VF attributes that the user has set into the FW through
the PF can be lost over a FW crash recovery.  Much like we
already replay the PF mac/vlan filters, we now add a replay
in the recovery path to be sure the FW has the up-to-date
VF configurations.
