Avoid calling qemu_mallocz with zero size
Currently qemu_mallocz calls malloc and handling of zero by malloc is
implementation defined behaviour:
http://www.opengroup.org/onlinepubs/7990989775/xsh/malloc.html
malloc(0) on AIX returns NULL[1] and qcow2 images without snapshots
are thus unusable
[1] Unless special Linux compatibility define is used when compiling
