Fix VLAN checks for SJA1105 DSA tc-flower filters

This fixes a ridiculous situation where the driver, in VLAN-unaware
mode, would refuse accepting any tc filter:

tc filter replace dev sw1p3 ingress flower skip_sw \
	dst_mac 42:be:24:9b:76:20 \
	action gate (...)
Error: sja1105: Can only gate based on {DMAC, VID, PCP}.

tc filter replace dev sw1p3 ingress protocol 802.1Q flower skip_sw \
	vlan_id 1 vlan_prio 0 dst_mac 42:be:24:9b:76:20 \
	action gate (...)
Error: sja1105: Can only gate based on DMAC.

So, without changing the VLAN awareness state, it says it doesn't want
VLAN-aware rules, and it doesn't want VLAN-unaware rules either. One
would say it's in Schrodinger's state...

Now, the situation has been made worse by commit 7f14937facdc ("net:
dsa: sja1105: keep the VLAN awareness state in a driver variable"),
which made VLAN awareness a ternary attribute, but after inspecting the
code from before that patch with a truth table, it looks like the
logical bug was there even before.

While attempting to fix this, I also noticed some leftover debugging
code in one of the places that needed to be fixed. It would have
appeared in the context of patch 3/3 anyway, so I decided to create a
patch that removes it.
