libqos: allow zero-size allocations

As part of streamlining the AHCI tests interface, it'd be nice
if specying a size of zero could be handled without special branches
and the allocator could handle this special case gracefully.

This lets me use the "ahci_io" macros for non-data commands, too,
which moves me forward towards shepherding all AHCI qtests into
a common set of commands in a unified pipeline.
