BluetoothSerial : Re-set _isRemoteAddressSet to false if connect() fails. (#6728)

Browse Source 
The internal _isRemoteAddressSet variable is set to true
when calling connect() functions. If connecting fails _isRemoteAddressSet
needs to be re-set to false, otherwise other functions, such as
discover() will fail without clear error messages.
