Fix data disconnect issue on G sub for C+G DSDS

On a DSDS Cdma+Gsm device, when data is registered on both Cdma and Gsm
subscriptions and DDS is on Gsm sub, if data deregister happens on Cdma
sub, data disconnect is getting propagated to connectivity service
irrespective of DDS, hence data is getting disconnected on Gsm sub.

Add code changes to block data disconnect getting propagated to
connectivity service when the subscription is not DDS.

Telephony: Few PIN/PUK fixes

Following changes have been made as part of this:
-> Changes done to display retry counter on wrong entry of
   PIN1,and message to indicate Code accepted/PIN1 blocked
   during PIN1 verification as per certain carrier requirements.
-> The current APIs that are used to verify the PIN and PUK only
   convey whether the operation succeeded or failed. As a result
   on ANY failure clients ask the user to re-enter the PIN.
   Add 2 new APIs that report the actual error code in case of
   failure.
-> Display the complete text including attempts remaining to
   unlock PIN on SimUnlockScreen if user entered incorrect PIN.
   On some devices the display text is ellipsized when trying to
   display on a single line.
