Would be a good catch ;) But after the recent discussion upstream [0],
the plan is to not patch QEMU, but set the option via RBD in the storage
plugin itself for EFI disks, that's why the hint is still passed along.
I added a comment that it's set via the storage layer in patch 09/15.

I think I'll send the next version of the storage patches relatively
shortly after part three (still quite a bit of splitting up
QemuServer.pm on the way, e.g for introducing a BlockJob module). I'll
try to send part three in the following days, I hope I get around to
also include blockdev-mirror there.

Part four is then hopefully the final one, doing all the version-guarded
switches and making all features work, fingers crossed :)
