"http" and "transfer" variables were missing in emulate_zero, so the
code would fail with NameError. This can happen only when communicating
with old imageio versions not supporting the "zero" feature.
Testing with qemu-img 2.12 show that we never send emulated zero request
because of the highestwrite mechanism, but it can break with older
qemu-img-rhev used on RHEL.
