[PATCH] drm/xe: Default auto_link_downgrade status to false

[Aradhya Bhatia]

xe_pcode_read() can return back successfully without updating the
variable 'val'. This can cause an arbitrary value to show up in the
sysfs file. This concern was flagged by the coverity static analysis
tool.

ALlow the auto_link_downgrade_status to default to 0 to avoid any such
complication.
