TDX guest doesn't support system_reset, so have to kill the old QEMU and start a new one to simulate the reset. This can be achieved by calling qemuProcessFakeRebootViaRecreate().
Simiar as FakeReboot, QEMU sends SHUTDOWN event with "host-signal" reason which can trigger another FakeReset. Check if a FakeReset is ongoing and bypass "host-signal" processing which originally comes from FakeReset.
Domain lock is already hold in qemuDomainReset() before calling qemuProcessFakeRebootViaRecreate(), so bypass locking in it.
