After sim unlock, Telephony manager return result is ready and

process get the password error message in showDefaultMessage.
So, the process should reset the mRemainingAttempts to be -1 after
confirming the sim state is ready. To reset the mRemainingAttempts
will make the showDefaultMessage not to trigger the wrong talkback.
