- (dtucker) [auth.c openbsd-compat/port-aix.c] Bug #1207: always call

loginsuccess on AIX immediately after authentication to clear the failed
   login count.  Previously this would only happen when an interactive
   session starts (ie when a pty is allocated) but this means that accounts
   that have primarily non-interactive sessions (eg scp's) may gradually
   accumulate enough failures to lock out an account.  This change may have
   a side effect of creating two audit records, one with a tty of "ssh"
   corresponding to the authentication and one with the allocated pty per
   interactive session.
