Bug in ldap_parse_result function (ITS#643)

[vtag@novell.com]

The following is against the development branch of the tree

If a user is using ldap result to obtain search results one message at a
time
and calls ldap_parse_result on one of those messages, i.e. the message
chain does not have an LDAP_RES_SEARCH_RESULT message
in the chain, ldap_parse_result returns a LDAP_DECODING_ERROR
instead of LDAP_NO_RESULTS_RETURNED.

The following patch corrects that problem:
