net/bnxt: fix VLAN filtering

net/bnxt: fix VLAN filtering

Currently, when hw-vlan-filter is enabled on testpmd, driver is
receiving all vlan packets. Instead, it should only receive untagged
packets and vlan packets for which the VLAN filter is programmed.
This is because, the default rule to match on MAC is not getting
deleted, when hw-vlan-filter is ON.

This patch fixes the problem, by deleting the default MAC rule and
programming a new rule to receive only untagged packets, when
hw-vlan-filter is enabled & another rule for each vlan, as and when
that vlan is configured on that port.
