Peter Krempa 0bfd11dd85 conf: Clear pointer to freed bitmap holding hostdev's 'origstates'
'virDomainHostdevDefClear' must clear the pointers too as it can be
invoked multiple times on the same object e.g. inside
qemuDomainRemoveHostDevice once via virDomainHostdevDefFree which skips
freeing the object if it's used via <interface> and thus has a 'net'
definition corresponding to it, and then subsequently via
virDomainNetDefFree.

Fix it by clearing the pointer along with freeing it.

Libvirt API for virtualization

Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
