xenbus: fix error exit in xenbus_init()

[ Upstream commit 44961b81a9e9059b5c0443643915386db7035227 ]

In case an error occurs in xenbus_init(), xen_store_domain_type should
be set to XS_UNKNOWN.

Fix one instance where this action is missing.

Fixes: 5b3353949e89 ("xen: add support for initializing xenstore later as HVM domain")
