Notify the sim state after callback registration.

Notify the register the current sim state right away in
registerSimStateCallback.Otherwise the register won't
receive any state until sim state gets changed again.
That will introduce a racing condition. If the sim state
changes to PUK_LOCKED after registering the callback, the
PUK unlock screen shows up. If the sim state changes to
PUK_LOCKED before registering, the PUK unlock screen won't
show.
