[Xen-devel] [PATCH v2] xen-disk: use g_new0 to fix build

[Olaf Hering <olaf@xxxxxxxxx>]

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")
