virNWFilterObjListFree: Don't leak nwfilters->objs

Browse Source 
When adding a nwfilter onto the list in
virNWFilterObjListAssignDef() this array is re-allocated to match
demand for new size. However, it is never freed leading to a
leak:

==26535== 136 bytes in 1 blocks are definitely lost in loss record 1,079 of 1,250
