In vlan_input(), if the network interface does not perform h/w based
vlan tag processing, the code will use bcopy() to remove the vlan
tag field but the code copies 2 bytes too many, which essentially
overwrites the protocol type field.
Also, a tag value of -1 is generated for unrecognized interface type,
which would cause an invalid memory access in the vlans array.
In addition, removed a line of dead code and its associated comments.
