[RFC] Bluetooth: Fix not sending link key negative reply

[Andrei Emeltchenko <Andrei.Emeltchenko.news@gmail.com>]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

If Link Keys are not loaded then HCI_LINK_KEYS is not set
and for HCI Event "Link Key Request" reply is not sent.
--
send as RFC since I did not get why we need this flag really.
