 Subject: Fix leaks in get_init_creds interface

 In Debian Bug 598032, Bastian Blank points out that there are two
 leaks in the get_init_creds interface:

 * Free ctx->request->padata after sending the KDC request so it is not
 overwritten the next time around the loop.

 * If options is NULL passed into krb5_get_init_creds_init, then set up
 a non-extended options structure so that krb5_get_init_creds_free will
 free the options.
