drivers/atm/ambassador: kill uninit'd var warning, and fix bug

An uninitialized variable warning illuminated an area where indeed the
variable was being used without initialization.  Unfortunately, after
verifying all such paths were fixed, the warning still appears.  So we
follow the initialization practice of other variables in this function.
