SNMP: eaton-ups-pwnm2-mib.c: two same numeric IDs in a lookup table

Lines 121 to 124 in dcbb2ba

	{ 10, "OL" /* high efficiency */, NULL, NULL },
	{ 11, "BYPASS" /* maintenanceBypass */, NULL, NULL },
	{ 11, "OL" /* essMode */, NULL, NULL },

@aquette : the two 11 values here, also in original code before the change - which one is right and which is a typo?

Looked for these OIDs, and it seems to be originally xupsOutputSource from XUPS-MIB (which only went up to 10 in enum values), supplanted by PowerMIB which as of 2011 included the maintenanceBypass(11) entry:

Similarly in CPQPower MIB at http://www.circitor.fr/Mibs/Html/C/CPQPOWER-MIB.php (up to 10'th enum value though, with a different OID prefix).

Was there a published Eaton MIB (probably after 2011) that actually mentioned an "ESS mode" in some fashion?

@arnaudquette-eaton : gentle bump :)

Feels curiously related to #2684 that adds "ESS mode" among other things to usbhid-ups generally and mge-hid.c in particular.
