nfp: flower: fix matching and pushing vlan CFI bit

This patch clears up some confusion around the meaning of bit 12
for FW messages related to VLAN and flower offload.

Pieter says:
It fixes issues with matching, pushing and popping vlan tags.
We replace the vlan CFI bit with a vlan present bit that
indicates the presence of a vlan tag. We also no longer set
the CFI when pushing vlan tags.
