qemu_process: Destroy domain's namespace after killing QEMU

Browse Source 
After QEMU is killed in qemuProcessStop() its mount namespace
doesn't exist anymore, because it was the only process running
there. Thus we should clear our internal flag that the domain has
namespace enabled so that seclabel restore code does not try to
enter it. We do the same in qemuProcessHandleMonitorEOF() but
when it is us, who decides to kill QEMU rather than QEMU quitting
we haven't seen EOF by the time qemuProcessStop() is called.
