nimble/sm: Use proper address types for confirm

Browse Source 
We should always use OTA address types for calculating confirm value.
Also if our OTA is an RPA, then always assume address type as random,
not address type that was used to start connection since this is
different kind of type (incompatible with actual address type).

Without this fix, pairing fails if privacy is used (e.g. we use RPA).

Note:
SM SC test cases were disabled with this fix since test vectors needs
to be recalculated due to input data (address type) changed.
