Fix toast is covered by PIN code screen after wrong pin

The error toast is displayed when user input wrong PIN
code three times, but at that moment the SIM PUK code input
page in SystemUI pop up and covers the toast, so the user
can't seen the error message.

Adjust the toast window layer, let the the toast pop up
over the SIM pin code input page.
