[Tizen] Do not fail if BLE is already connected

[arkq]

Problem

If commissionee device is already connected (e.g. previous commissioning has failed after BLE connection, and it was restarted), Tizen will report BLE connection as failed...

Changes

• handle BT_ERROR_ALREADY_DONE result code as not an error

Testing

Tested manually with chip-tool pairing ble-wifi 1 <SSID> <pass> 20202021 3840 on Tizen:

I/CHIP    (  914): DL: Gatt Connection State Changed [4265607427]: Connected         <--- 4265607427 == BT_ERROR_ALREADY_DONE
I/CHIP    (  914): DL: Device Connected [B8:27:EB:5E:BA:83]
I/CHIP    (  914): DL: AddConnectionData for [B8:27:EB:5E:BA:83]
