sdap_get_generic_ext_send: check if we a re still connected
At the beginning of a LDAP request we check if we are connecte and have a valid sdap handle. But for some requests more than one LDAP operation, typically a search, is needed. Due to the asynchronous handling of LDAP request it might be possible that a second request might detect a server error and close the connection while the first request just finished one LDAP search and wants to start a new LDAP search. This patch tries to make sure that there is a valid sdap handle before sending a LDAP search to the server. Fixes
