John Ferlan 77fb4c4f9e storage_backend: Fix issue with allocation of 0 length volume 
Commit id '532fef36' added a call to fallocate() and some error
handling based on whether or not the function existed. This new
call resulted in libvirt-cim/cimtest failures when attempting to
create a volume with "0" (zero) allocation value. The failure is
logged as:

Oct  9 07:51:33 localhost libvirtd[8030]: cannot allocate 0 bytes in
file '/var/lib/libvirt/images/cimtest-vol.img': Invalid argument

This can also be seen with virsh vol-create-as:

error: Failed to create vol test
error: cannot allocate 0 bytes in file '/home/vm-images/test': Invalid
argument

error: Failed to create vol test
error: cannot allocate 0 bytes in file '/home/vm-images/test': Invalid
argument

It turns out fallocate() will return EINVAL when the incoming 'len'
(or allocation) value is 0 (or less).

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
