Smartcard tls logon fix (#7709)

Browse Source 
* Early return authenticate if TLS smartcard logon

* Removed obsolete SmartcardPin and unified AuthenticateEx calls

* Remove password-is-pin from command line

The setting is implied by smartcard-logon and only of interest in
server side code, so the setting is useless

* Rework AUTH_SMARTCARD_PIN

Just prompt for PIN and not user/domain if this is requested.

* Fixed a memory leak in nla.c

* Align credentail prompt

* Handle AUTH_NLA & smartcard, just ask for PIN

* Added assertions, removed duplicate password prompt check

* Move smartcard logon after credential prompt
