[libvirt] [PATCH 1/2] Don't skip zero'ing end of volume file when inputvol is shorter than newvol

[Laine Stump]

A missing set of braces around an error condition caused us to skip
zero'ing out the remainder of a new volume file if the new volume was
longer than the original (the goto was supposed to be taken only in
the case of error, but was always being taken).
