xenbus: Unregister reboot notifier on init failure
xs_init() registers xs_reboot_nb before initializing XenStore
communications and starting xenwatch. If either operation fails, the
notifier remains registered and a later initialization attempt can hit a
duplicate registration.
Check the notifier registration result and unregister it on every
subsequent failure path.
Fixes: fd8aa9095a95 ("xen: optimize xenbus driver for multiple concurrent xenstore accesses")
