[c-nsp] MPLS QOS on ME3600 not working???

This is similar, but not the right bug. This bug is fixed in the 15.3.3S
train and it is specific to class-map ACLs that are matching on L4 ports.
In Adam's case we are on later code and there are no ACLs matching L4 ports.

I've updated the release note to indicate the requirement of L4 information
in the ACL, it should change on cisco.com tomorrow.
