Expect rmw_destroy_wait_set to ret RMW_RET_INVALID_ARGUMENT

[christophebedard]

https://github.com/ros2/rmw/pull/275 changed the rmw_destroy_wait_set() API documentation to indicate that it returns RMW_RET_INVALID_ARGUMENT if wait_set is NULL. However, this wasn't the case in practice in the implementations of rmw_destroy_wait_set() or in the relevant test.

Change the test here to expect RMW_RET_INVALID_ARGUMENT.

Required rmw implementation PRs:

• https://github.com/ros2/rmw_cyclonedds/pull/498
• https://github.com/ros2/rmw_fastrtps/pull/766
• https://github.com/ros2/rmw_connextdds/pull/152
• (rmw_zenoh already returns RMW_RET_INVALID_ARGUMENT in this case)
