Give virNWFilterVarCombIterNext saner semantics

Browse Source 
The virNWFilterVarCombIterNext method will free its
parameter when it gets to the end of the iterator.
This is somewhat misleading design, making it appear
as if the caller has a memory leak. Remove the free'ing
of the parameter and ensure that the calling method
ebiptablesCreateRuleInstanceIterate free's it instead.
