Python 3.11: Fix a memory leak switching to greenlets.

This leak was present in the original implementation of Python 3.11 support (#306)

Fixes #328 and fixes https://github.com/gevent/gevent/issues/1924 ; I have run gevent's test suite locally on 3.11 with this fix without seeing any regressions.
