[PATCH v2 2/3] xen/store: do not store local values in xen_start_info

From: Roger Pau Monne
Date: Wed May 09 2018 - 06:22:11 EST


There's no need to store the xenstore page or event channel in
xen_start_info if they are locally initialized.

This also fixes PVH local xenstore initialization due to the lack of
xen_start_info in that case.
