Bluetooth: SMP: Reject legacy pairing early in SC only mode

Browse source 
Reject the security request immediately when receiving a security
request that does not support LE Secury Connections pairing.
This would have been rejected during the pairing procedure, but
PTS testing expects the security request to be rejected.
