Bug 1072 -Add OF13 pre-req for PCP match in TestCommandProvider

Bug 1072 -Add OF13 pre-req for PCP match in TestCommandProvider

-OXM_OF_VLAN_PCP requires a VID match pre-req. The function
f80() results in a OFPBAC_MATCH_INCONSISTENT since it is
only matching on nw_dst and not a vid.

-Patching this seperate from Bug-1072/Patch-ba79f4f in
case there was a specific reason for this combination
that is outside the spec.

Field: OXM_OF_VLAN_PCP
Dependency: VLAN VID!=NONE
Reference: See table 10, section A.2.3.5 for validation
