bnx2x: Remove configured vlans as part of unload sequence.
[ Upstream commit 04f05230c5c13b1384f66f5186a68d7499e34622 ]
Vlans are not getting removed when drivers are unloaded. The recent storm
firmware versions had added safeguards against re-configuring an already
configured vlan. As a result, PF inner reload flows (e.g., mtu change)
might trigger an assertion.
This change is going to remove vlans (same as we do for MACs) when doing
a chip cleanup during unload.
