Fix: LED state not changes for UpperCriticalthresh

Issue: LED state is in Blinking Green after setting the
       'Upper Critical threshold'.

RootCause: A Typo in the event name used in source code.

Fix:
After setting the Threshold value expected LED status should be
   "blinking Amber "

Tested:

Initial LED state:
ipmitool raw 0x30 0xb0
 20 --> Solid Green

1. Patch the  'Upper Critical threshold' value to 'Inlet_BRD_Temp'
PATCH : https://<bmcip>/redfish/v1/Chassis/<Baseboard>/Thermal
patch body:
{
   "Temperatures":[
      {
         "MemberId":"Inlet_BRD_Temp",
         "ReadingCelsius":120.0
      }
   ]
}

Response :
{
    "@odata.id": "/redfish/v1/Chassis/<Baseboard>/Thermal",
    "@odata.type": "#Thermal.v1_4_0.Thermal",
    "Fans": [],
    "Id": "Thermal",
    "Name": "Thermal",
    "Temperatures": []
}

LED state changed
ipmitool raw 0x30 0xb0
 04 --> Blinking Amber
