kdc: _kdc_find_etype prevent NULL dereference
If use_strongest_session_key and no keys are found the return
code will be set to KRB5KDC_ERR_ETYPE_NOSUPP. However, before
exiting if the principal is a weak exception then the return
code will be set to success and a NULL key pointer will be
dereferenced. Skip the weak exception check if the return
code is non-zero.
