Bluetooth: Don't try to confirm locally initiated SMP pairing
In the case that the just-works model would be triggered we only want to confirm remotely initiated pairings (i.e. those triggered by a Security Request or Pairing Request). This patch adds the necessary check to the tk_request function to fall back to the JUST_WORKS method in the case of a locally initiated pairing.
