[PATCH 5.10 127/663] net: dsa: felix: perform teardown in reverse order of setup

[ Upstream commit d19741b0f54487cf3a11307900f8633935cd2849 ]

In general it is desirable that cleanup is the reverse process of setup.
In this case I am not seeing any particular issue, but with the
introduction of devlink-sb for felix, a non-obvious decision had to be
made as to where to put its cleanup method. When there's a convention in
place, that decision becomes obvious.
