virnetdevopenvswitch: Simplify OVS_VSCTL cmd creation

Browse Source 
Every time we create new virCommand of OVS_VSCTL it must be
followed by virNetDevOpenvswitchAddTimeout() call which adds the
--timeout=X argument to freshly created cmd. Instead of having
this as two separate function calls it can be just one.
