Simplify k5_preauth_tryagain()

When retrying pre-authentication for an error, try only the module for
the selected preauth type, not all preauth types in the original
method data.  Pass the error and its padata to k5_preauth_tryagain()
explicitly, so that those fields of krb5_init_creds_context are only
referenced in get_in_tkt.c.  Handle a degenerate case in
init_creds_step_reply() to simplify the code in
init_creds_step_request().
