Fix Windows notifications not being sent on reconnection.

When Windows bonds with a device and subscribes to notifications/indications of the device characteristics it does not re-subscribe on subsequent connections.
If a notification is sent when Windows reconnects it will overwrite the stored subscription value in the NimBLE stack configuration with an invalid value which results in notifications/indications not being sent.

This change will ensure that no notification or indication is sent before authentication upon reconnection, avoiding the described issue described above.
