* agent: use primary key index in setRcvServiceAssocs (#1783)

* agent: use primary key index in setRcvServiceAssocs

Previous WHERE rcv_id = ? did not match the (host, port, rcv_id)
primary key prefix and fell back to a table scan via
idx_rcv_queues_client_notice_id. With ~390k rows per queue, each
update in a 1350-row batch scanned the whole table, yielding ~290s
per batch and a multi-hour rcv-services migration.

* agent: pass SMPServer explicitly to setRcvServiceAssocs

Avoid extracting host/port from the first queue inside setRcvServiceAssocs.
The caller already has SMPServer in scope (from tSess) and the call chain
is short, so threading it through is simpler than inspecting the list.
Removes the empty-list guard from setRcvServiceAssocs (it remains in
processRcvServiceAssocs).
