g_malloc0_n is available since glib-2.24. To allow build with older glib
versions use the generic g_new0, which is already used in many other
places in the code.

Fixes commit 3284fad728 ("xen-disk: add support for multi-page shared rings")

Can you provide information about which 
distrib/release/version/[packages?] you used? So we might add the same 
setup in QEMU continuous integration system.

Thank,

Phil.

I do have a build system with our oldest supported glib
version (it's my OSX box), and I have a feeling one of the
patchew centos configs does this too, but I guess neither
of them have the Xen headers to enable the Xen code,
which is why this one slipped through.

thanks
