[Pgpool-committers] pgpool - pgpool-II: Remove unused argument

[User T-ishii]

Log Message:
-----------
Remove unused argument first_ready_for_query_received from
pool_process_query.  Also change argument "connection_reuse" to
reset_request which is more appropreate one.
While processing reset_request is true, we don't read from frontend
any data because after received terminate request, anything from
from frontend must be bogus and should be ignored.
Remove unsed variable first_ready_for_query_received from do_child.
