include/hw/xen/xen_common: return error from xen_create_ioreq_server
This is done to prepare for enabling xenpv support for ARM architecture.
On ARM it is possible to have a functioning xenpv machine with only the
PV backends and no IOREQ server. If the IOREQ server creation fails,
continue to the PV backends initialization.
