be2net: clear vlan-promisc setting before programming the vlan list 

The Lancer FW has a bug due to which in some cases vlan-promisc setting
is cleared eventhough the vlan-list programming did not succeed (via
VLAN_CONFIG) cmd. The driver has no way of knowing if the vlan-promisc
mode was cleared or not when this cmd fails. To work around this issue,
this patch first explicitly clears the vlan-promisc mode via RX_FILTER
cmd and then tries to program the vlan list.
