Do not reset keyguard when SIM is ready

We used to reset the keyguard because the SIM could potentially
require a PIN/PUK but most of the time it won't be true.

The SIM might take a while to load, which means that the user
would swipe up to unlock and then the password view would disappear
because the SIM became READY.

Now, we're resetting the keyguard only when the SIM actually requests
a PIN or PUK.
