… host_electrical_interface, connector_dict (#206) Due to wrong page selection, the eeprom read returned a value 0xff which was an invalid key into connector_dict[]. Now we verify the key validity before accessing the dict element. The fix for why the eeprom read returned 0xff is being investigated separately. Signed-off-by: Prince George <prgeor@microsoft.com>

On first run, the PSU master-led on supervisor of modular-chassis is not set. Description The PSU master-led on modular chassis indicates the power-buget status. Similar to individual PSU leds that are set on first_run, the master-led also will be set to based on initial status (RED or GREEN with LED status ON). Motivation and Context Without the forced setting of first_run, the master-led status will default to per vendor default. In some cases, this could be amber blinking etc

Motivation and Context
Due to wrong page selection, the eeprom read returned a value 0xff which was an invalid key into connector_dict[]. Now we verify the key validity before accessing the dict element. The fix for why the eeprom read returned 0xff is being investigated separately.
How Has This Been Tested?
Verified no xcvrd crash across multiple reboots on str-DellEmc-z9332f-032.
