This patch fixes double pairing issues with Secure Simple
Paring support. It was observed that when pairing with SSP
enabled, that the confirmation will be asked twice.

This also causes bug when initiating SSP connection from
Windows Vista.

The reason is because bluetoothd does not store link keys
since HCIGETAUTHINFO returns 0. Setting default to general
bonding fixes these issues.
