Null pointer deref in kadmind [CVE-2012-1013]

The fix for #6626 could cause kadmind to dereference a null pointer if
a create-principal request contains no password but does contain the
KRB5_KDB_DISALLOW_ALL_TIX flag (e.g. "addprinc -randkey -allow_tix
name"). Only clients authorized to create principals can trigger the
bug. Fix the bug by testing for a null password in check_1_6_dummy.
