Settings: Disable USB preferences if USB signaling is off

* When developer options is turned
  off and on again, 'Default USB
  configuration' and 'Disable USB
  audio routing' should not be enabled
  if USB data signaling is disabled.

Manual testing:
* Disable USB data signaling
* Verify preferences are disabled
* Turn developer options off and on
* Verify preferences remain disabled
