Prevent buffer overrun in old leashdll functions
Leash_kinit_dlg() and Leash_changepwd_dlg() use a dialog callback
function PasswordProc(). If the caller supplies a principal name
longer than 254 bytes via lpdlginfo->principal, PasswordProc() writes
beyond the bounds of a stack-allocated array. Reported by Rahul
Hoysala.
These functions are both deprecated in favor of _ex variants (which
use a different dialog callback) and are not used by Leash.
