Karsten Graul 0d9ddf515c net/smc: improved fix wait on already cleared link ...

commit 95f7f3e7dc upstream.

Commit 8f3d65c166 ("net/smc: fix wait on already cleared link")
introduced link refcounting to avoid waits on already cleared links.
This patch extents and improves the refcounting to cover all
remaining possible cases for this kind of error situation.
