staging: vt6655: fix camelcase in ldBmThreshold

Replace camel case variable ldBmThreshold with snake case
variable dbm_threshold. ldBmThreshold is in hungarian notation, where
"l" is for long and "dbm" is for decibel-milliwatt (signal strenght).
This variable contain's signal strenght threshold in dbm.
