Simplify IMMS#updateInputMethodsFromSettingsLocked() a bit

This CL simplifies

  InputMethodManagerService#updateInputMethodsFromSettingsLocked()

a bit by explicitly having a local instance "userId" instead of using

  settings.getUserId()

as a synonym of it.

This is a mechanical refactoring CL, which should have no behavior
change.
