Revert "call ovsrcu_exit() before exit in ovn-northd and ovn-controll…

…er to make valgrind happy"

This reverts commit 6849811.

The function run_update_worker_pool() doesn't exist on branches <=
22.03 as the parallelization code changed in newer branches.  There's no
need to complicate things just to make valgrind happy.

Fixes: 6849811 ("call ovsrcu_exit() before exit in ovn-northd and ovn-controller to make valgrind happy")
