Function qemuProcessUpdateDevices was called at qemuProcessReconnect
when we detach net device lively and killed libvirtd service at middle.
qemu detached the device but libvirtd don't save it at runDir. when
libvirtd restart, libvirtd will detach net device but qemu will return
fail because device was not found. then libvirtd qemuProcessReconnect
failed and goto error. libvirtd kill qemu. To avoid qemu is killed by
libvirtd, qemuDomainRemoveDevice will not return failed.
