ofproto-dpif-xlate: Correct check for MPLS LSE

Browse Source 
zero is a valid MPLS LSE so it is not valid check against
that value for MPLS LSE presence. Instead, check against
the flow's dl_type which should be an MPLS type if an LSE is present.

This problem appears to have been introduced by
b2dd70be13 ("Native Set-Field action.").
