Bluetooth: Use actual encryption key size for SMP over BR/EDR
When pairing over SMP over BR/EDR the generated LTK has by default the same key size as the BR/EDR Link Key. Make sure we don't set our Pairing Request/Response max value to anything higher than that. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
