[PATCH] Bluetooth: Respect local MITM req in io_cap reply

[johan.hedberg@gmail.com]

From: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com>

If host requires MITM protection notify that to controller in
io capabilities reply even if the remote device requires no bonding.

If it is not respected, host can get an unauthenticated link key while
it expects authenticated one.
