Subject: [PATCH] adapter: Fix up address type when loading keys

Due to kernel change 59b047bc9808
("Bluetooth: MGMT/SMP: Fix address type when using SMP over BREDR/LE")
some keys maybe store using the wrong/invalid address type as per MGMT
API, so this attempts to fix them up.

Fixes: https://github.com/bluez/bluez/issues/875
Upstream-Status: Backport [366a8c522b648f47147de4852c5c030d69b916b3]
