#1657943 — [PATCH 4.9 43/94] acpi, nfit: Fix the memory error check in nfit_handle_mce()

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

------------------

From: Vishal Verma <vishal.l.verma@intel.com>

commit fc08a4703a418a398bbb575ac311d36d110ac786 upstream.

The check for an MCE being a memory error in the NFIT mce handler was
bogus. Use the new mce_is_memory_error() helper to detect the error
properly.
