[PATCH 3.12 065/127] ACPI / APEI: Fix incorrect return value of ghes_proc()

[Jiri Slaby]

From: Punit Agrawal <punit.agrawal@xxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 806487a8fc8f385af75ed261e9ab658fc845e633 upstream.

Although ghes_proc() tests for errors while reading the error status,
it always return success (0). Fix this by propagating the return
value.

Fixes: d334a49113a4a33 (ACPI, APEI, Generic Hardware Error Source memory error support)
