As the Xen backend operations were abstracted out into a function table to
allow for internally emulated Xen support, we missed the xen_init_pv()
code path which also needs to install the operations for the true Xen
libraries. Add the missing call to setup_xen_backend_ops().
Fixes: b6cacfea0b38 ("hw/xen: Add evtchn operations to allow redirection to internal
emulation")
