[libvirt] [PATCH] qemu: Don't crash when create fails early

Since commit 714080791778e3dfbd484ccb3953bffd820b8ba9 we are generating socket path later than before -- when starting a domain. That makes one particular inconsistent state of a chardev, which was not possible before, currently valid. However, SELinux security driver forgot to guard the main restoring function by a check for NULL-paths. So make it no-op for NULL paths, as in the DAC driver.
