fix vlan in 8139cp on big-endian
Layout of opts2 is : MSB(vlan_tag) : LSB(vlan_tag) : flags : 0 : regardless of the host endianness. On little-endian the current code ends up with the right values, but on big-endian it blows. In r8169.c the same bug had been fixed in commit d35da12a40426184b1d0844104b1d464753eba19 (r8169: endianness fixes).
