Fixed a bug that failed specifying the value 0 on VLAN ID field for a match condition...

- Fixed MatchType class to allow the value 0 on VLAN ID field for VLAN untagged frames.
- Changed FlowConverter class to convert the value 0 on VLAN ID field of SAL Flow into the value 0xffff of OF Flow, and vice-versa.
