SystemUI: fix up navigation cursor keyevent flags

Volume cursor controls use slightly different flags to keep the cursor
within the field. Match them in the SystemUI for consistent (and better)
behavior.

MountService: Check for null pointer when looking for vold code

* There is actually no code path that will set an event into
  NativeDaemonConnectorException, so any reference to the event code
  will result in a null pointer exception, taking down MountService and
  the rest of the system with it.

SystemUI: fix up initial cursor down flags on nav bar

We were using the regular flags for the initial ACTION_DOWN event so the
FLAG_KEEP_TOUCH_MODE was not being passed and allowed the cursor to jump
out of bounds slightly.

SystemUI: fix nav bar layout while toggling cursor keys with an IME up

Previously there was no option to have the IME up on that settings
screen so this was not a concern before; however, with the addition of
searchable settings, it seems users are now trying to toggle it with the
IME active, putting the nav bar in a strange state becuase it did not
restore the previous states properly.
