This wasn't enforced at all thus a query would return all available matches
without limit.

SL_PAGESIZE is the number of entries we want to process per paged search result
set. This is different from MAX_SL_RESULTS which ought to be a default maximum
value for total number of results returned for a search query.

Calling tevent_req_error() triggers a HTTP reconnect in mds_es_search_done() as
mds_es_search_recv() returns the error so we call mds_es_reconnect_on_error().
slq (which is s->slq) or s->mds_es_ctx will be NULL if the user closed a search
or disconnected a share with an active mdssvc IPC pipe, no need to trigger a
HTTP reconnect for those cases.

This was dead code: before this patchset noone set s->mds_es_ctx->mds_ctx to
NULL. A previous commit changed that so now the mds_es_ctx destructor sets
s->mds_es_ctx to NULL if a search "s" was currently in-flight.

This is needed to ensure searches that are scheduled more then once to the
Elasticsarch server (because the first run didn't return all results) get
removed from the list of searches in case the user closes the query.

When a search is in-flight and currently being processed against the
Elasticsearch server, we set s->pending. In the destructor of "s" we check "pending"
and reject deallocation of the object.
One instance where "s" is requested to be deallocated is when the client closes
the top-level per-share search connection. This will implicitly close all
searches associated with the mds_ctx from mds_ctx_destructor_cb():
while (mds_ctx->query_list != NULL) {
/*
* slq destructor removes element from list.
* Don't use TALLOC_FREE()!
*/
talloc_free(mds_ctx->query_list);
}
So when this happens the Elasticsearch backend query object stays around,
alongside with any active tevent_req request and a tevent_req timer set with
tevent_req_set_endtime() in mds_es_search_send().

This makes the calls to mds_es_search_set_pending() and
mds_es_search_unset_pending() symmetric. No change in behaviour.

Both codepaths were mds_es_search_unset_pending() is currently called end up
going through the higher level callback mds_es_search_done(). Moving the call to
mds_es_search_unset_pending() ensures we call it consistently and don't miss it
in some error code path.
Otherwise no change in behaviour.
