Bug description:
[Impact]
* Read from /dev/mem and scan DMI tables is dangerous, if /dev/mem is
not stable to read, it will cause ipmi-locate crash.
[Test Case]
* `sudo ipmi-locate` shall not crash
[Regression Potential]
* Reading from DMI tables is sysfs is more stable then reading from
/dev/mem and if DMI tables is not available ipmi-locate will use the
old way to search in /dev/mem. I believe its low regression risk
----
Similiar to bug 1499838 but not 100% same.
ipmi-locate looks into /dev/mem for DMI tables and crash when DMI
tables are not in accessible memory region. Kernel > v4.2 provides
/sys/firmware/DMI/tables/DMI which is a much safer place to read.
