tests: fix failures due to not unmounting $M2 (/mnt/glusterfs/2)

Our failure to unmount meant that both mkdir and rmdir would fail in
cleanup().  Because one of those mkdirs was the last thing cleanup()
executed, it would fail, so the test would fail, so the entire
regression run would fail.  The fix has two parts.

(1) Unmount the offending directory.

(2) Make sure cleanup() returns success even if that last mkdir
    failed.

That might keep us from consistently blowing up regression runs on the
very first tests (basic/afr/data-self-heal.t) that we execute.
