novatel-lte: implement load_unlock_retries
This patch implements load_unlock_retries() for the Novatel LTE modem by using the AT$NWPINR? command to query the number of retries left for entering PIN1 or PIN2. Ported from the original patch by Arman Uguray <armansito@chromium.org>: https://chromium-review.googlesource.com/c/58118
