Thanks, I guess it's fine to don't leak memory here, but in any case this is
doomed to fail, no further progress is going to be made if Dom0 build fails,
hence that's why memory leaks here are not really meaningful.

This one doesn't need the goto, there's nothing leaked here (although there's
also no problem in doing in that way).
