Subject: [PATCH] Revert "perf map: Fix dso->nsinfo refcounting"

This makes 'perf top' abort in some cases, and the right fix will
involve surgery that is too much to do at this stage, so revert for now
and fix it in the next merge window.

This reverts commit f63ff23f7d45b07bf6db59213d8eee7ddb7ec700.
