[libvirt] [PATCH] parallels: fix libvirt crash if parallelsNetworkClose fails
If, by any reason, parallelsNetworkClose fails it dereferences
newly allocated privconn->networks via virObjectUnref, which in
turn deallocates its memory.
Subsequent call of parallelsNetworkClose calls virObjectUnref
that leads to double memory free. To prevent this we should zero
privconn->networks to make all subsequent virObjectUnref be safe.
