Keyguard: Don't lock if SIM is NOT_READY

Fixes an issue with MVNOs where the lockscreen
would show in response to a virtual SIM switch.

Now we no longer lock with NOT_READY.

Change-Id: I520200311a5ae3218f1743b1fc9a568c39933ebf
Fixes: 33386149
Bug: 30997251
Test: Set up secure lockscreen, insert Fi SIM, dial *#*#346398#*#*, verify screen does not lock, eject SIM, verify screen locks.
