readwritesplit.c:routeQuery if target is master but it is found out when get_dcb returns that master DCB has changed, routeQuery fails and logs to trace that master changed.
Fixed use of uninitialized variable.
readwritesplit.c:get_dcb assumed thet get_root_master_bref always returns non-null pointer. Changed it so that get_dcb_returns if it doesn't get master bref pointer.
