It is a trivial change of replacing a goto with an assignment and moving 
it a few lines down. It reduces "jumpiness" within that function and is 
a cleaner version. On the more practical side, it was done in 
preparation for some other changes I have coming up, which touch that 
function and work a lot better with the cleaned-up failure path. The 
next patch was delayed (due to a dependency) but as long as I was doing 
code cleanup, I saw no reason not to also clean up the failure path as 
part of this series.
