Use base class link state in case of Win intf stats

Browse Source 
After this change adapter_ and linkStateOid_ members are no longer
required in case of Windows Interface stats, so don't initialize them.

Also remove all references to them in ifstats mode - the change in
has/setExclusiveControl also fixes the non-working bindconfig - the
problem was the portname being derived in those functions was not
correct causing bindconfig to fail - bindconfig itself probably never
had a problem.
