Guido Günther 269d39afe5 storage: only run safezero if allocation is > 0 
While a zero allocation in safezero should be fine it isn't when we use
posix_fallocate which returns EINVAL on a zero allocation.

While we could skip the zero allocation in safezero_posix_fallocate it's
an optimization to do it for all allocations.

This fixes vm installation via virtinst for me which otherwise aborts
like:

   Starting install...
   Retrieving file linux...               | 5.9 MB     00:01 ...
   Retrieving file initrd.gz...           |  29 MB     00:07 ...
   ERROR    Couldn't create storage volume 'virtinst-linux.sBgds4': 'cannot fill file '/var/lib/libvirt/boot/virtinst-linux.sBgds4': Invalid argument'

The error was introduced by e30297b0 as spotted by Chunyan Liu
