hrStorageType defines the type of information provided via SNMP handled by hr_mem. Very often invalid values for hrStorageType are being provided, which leads to unhandled ValueError() exceptions. This change makes the plugin not crash on invalid values but instead return a special string "unknown" as value for hr_type which then can be handled properly by the checks which handle the data provided by hr_mem.
