krb5_server_decrypt_ticket_keytab wrongly succeeds
If krb5_server_decrypt_ticket_keytab doesn't find a key of the
appropriate enctype in an iterable keytab, it returns 0 (without
decrypting the ticket) due to a misplaced initialization of retval.
This bug causes kinit -k to claim "keytab entry valid" when it
shouldn't. Reported by mark@mproehl.net.
