Subject: [PATCH 2/3] EDAC/igen6: Initialize edac_op_state according to the configuration data

From: Qiuxu Zhuo <qiuxu.zhuo@...el.com>

Currently, igen6_edac sets edac_op_state to EDAC_OPSTATE_NMI, while the
driver also supports memory errors reported from Machine Check. Initialize
edac_op_state to the correct value according to the configuration data
that the driver probed.
