krb5_gssapi: Only process challenge when present 

This wouldn't cause a problem because of the way the function is called,
but prior to this change, we were processing the challenge message when
the credentials were NULL rather than when the challenge message was
populated.

This also brings this part of the Kerberos 5 code in line with the
Negotiate code.
