[libvirt] [PATCH v2 08.5/12] qemu: Create a set of macros to handle setting block iotune values

Rework the code to create a couple of macros to hide all the comparisons
for each of the 6 "types" of data fields to collect. Each macro will check
the base name, then the base name + "_max", and base name + "_max_length".
