Subject: [PATCH 4/5] rasdaemon: use MCA error msg as error_msg

In the case of machine-checks which do not have a model-specific MCA
error code but have an architectural code only, mce_event.error_msg
becomes empty then you don't know what happened.

(snip)
MCE records summary:
	1  errors
          ^
          empty!

(snip)
MCE events:
1 2015-06-12 00:21:46 +0900 error: , mcg mcgstatus= 0, mci Corrected_error
                                  ^
                                empty!

Error_enabled, mcgcap=0x07000c16, status=0x9c0000000000017a, addr=0x204fffffff, misc=0x4004000000000080, walltime=0x557b0db2, cpu=0x00000001, cpuid=0x000306f3, apicid=0x00000002, bank=0x00000003

In such a case, let's use the content of mcastatus_msg as error_msg
instead.

MCE records summary:
	1 Generic CACHE Level-2 Eviction Error errors

MCE events:
1 2015-06-12 02:39:04 +0900 error: Generic CACHE Level-2 Eviction Error, mcg mcgstatus= 0, mci Corrected_error Error_enabled, mcgcap=0x07000c16, status=0x9c0000000000017a, addr=0x204fffffff, misc=0x4004000000000080, walltime=0x557b1f22, cpu=0x00000001, cpuid=0x000306f3, apicid=0x00000002, bank=0x00000003
