Subject: [PATCH] Fix systemctl kexec exit status check
There's always an error printed even when the systemctl kexec command does
succeed. That's because systemctl executes it asynchronously, but the emu
loader seems to expect it to be synchronous and that should never return.
Also, it's wrong to test if kexecute == 1 since we already know that's the
case or otherwise the function wouldn't had called grub_fatal() earlier.
Finally, systemctl kexec failing shouldn't be a fatal error since the emu
loader fallbacks to executing the kexec command in case of a failure.
