vlan: Calling vlan_hwaccel_do_receive() is always valid.

Browse source 
It is now acceptable to receive vlan tagged packets at any time,
even if CONFIG_VLAN_8021Q is not set.  This means that calling
vlan_hwaccel_do_receive() should not result in BUG() but rather just
behave as if there were no vlan devices configured.
