Set ofproto's connmgr pointer to NULL after the connmgr has been destructed, and check for NULL when sending a flow removed notification. Verified by sending the flow removed message unconditionally and observing numerous core dumps in the test suite. Found by inspection. Fixes: f695ebfa ("ofproto: Postpone sending flow removed messages.") Signed-off-by: Jarno Rajahalme <jarno@ovn.org> Acked-by: Ben Pfaff <blp@ovn.org>
