pam_succeed_if: avoid returning garbage for empty configuration

If pam_succeed_if is used without any options the return value ret will
never be assigned a value.  Since the case where the counted number of
options is zero will print 'no condition detected; module succeeded'
set the return value to PAM_SUCCESS.

Reported by Clang analyzer:

    pam_succeed_if.c:578:2: warning: Undefined or garbage value returned to caller [core.uninitialized.UndefReturn]
      578 |         return ret;
          |         ^~~~~~~~~~
