On iDRAC/PowerEdge hosts the "PowerEdge Health" service went to UNKNOWN with IndexError: list index out of range and produced a crash report when the SNMP walk under the Dell iDRAC health tree returned no rows.

An empty response from the device is now treated as "no section data": the "PowerEdge Health" service reports that no data was received instead of crashing.
