qemu: Remove hostdev entry when freeing the depending network entry
When using a <interface type="network"> that points to a network with hostdev forwarding mode a hostdev alias is created for the network. This allias is inserted into the hostdev list, but is backed with a part of the network object that it is connected to. When a VM is being stopped qemuProcessStop() calls networkReleaseActualDevice() which eventually frees the memory for the hostdev object. Afterwards when the domain definition is being freed by virDomainDefFree() an invalid pointer is accessed by virDomainHostdevDefFree() and may cause a crash of the daemon. This patch removes the entry in the hostdev list before freeing the depending memory to avoid this issue. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1000973
