[PATCH 3/7] ACPI-APEI-HEST: Move an assignment in hest_ghes_dev_register()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 5 Sep 2016 21:15:22 +0200

Move one assignment for a data structure member in one local variable
so that its setting will only be performed after a corresponding memory
allocation succeeded by this function.
