Honestly this entire patch can be dropped because its not correct.
qemuFindQemuImgBinary() only looks up the path to the binary the first
time and then caches it from there on in. So you should always be
using qemuFindQemuImgBinary(). As far as the addition to the startup
of looking it up, it seems like that's really a pre-mature
optimization for your second patch.
So I'd have to say NACK on this change.
