Revert "Fix teardown error reporting when --maxfail=1 (pytest-dev#11721)"

Fix pytest-dev#12021.
Reopens pytest-dev#11706.

This reverts commit 12b9bd5.

This change caused a bad regression in pytest-xdist:
pytest-dev/pytest-xdist#1024

pytest-xdist necessarily has special handling of `--maxfail` and session
fixture teardown get executed multiple times with the change.

Since I'm not sure how to adapt pytest-xdist myself, revert for now.

I kept the sticky `shouldstop`/`shouldfail` changes as they are good
ideas regardless I think.
