Bluetooth: Remove unnecessary 'send' parameter from smp_failure()

The send parameter has only been used for determining whether to send a
Pairing Failed PDU or not. However, the function can equally well use
the already existing reason parameter to make this choice and send the
PDU whenever a non-zero value was passed.
