adapter: Load keys that should be blocked by the kernel

This change accomplishes 2 things:
 1. Drop device security data from previously paired devices
 using blocked keys.
 2. Send the list of known bad keys that should be blocked to the kernel
 if supported.

In particular keys from the Google Titan Security key are being
blocked.
