Subject: [PATCH] Bluetooth: Fix incorrectly setting HCI_CONNECTABLE

Since page scan might be enabled by Add Device we should not implicitly
set connectable whenever something else than Set Connectable changes it.
This patch makes sure that we don't set HCI_CONNECTABLE for these cases
if there are any entries in the white list.
