net/mlx5e: When changing XDP program without reset, take refs for XSK…
… RQs [ Upstream commit e5eb013 ] Each RQ (including XSK RQs) takes a reference to the XDP program. When an XDP program is attached or detached, the channels and queues are recreated, however, there is a special flow for changing an active XDP program to another one. In that flow, channels and queues stay alive, but the refcounts of the old and new XDP programs are adjusted. This flow didn't increment refcount by the number of active XSK RQs, and this commit fixes it.
