  Log Message:
  -----------
  Free connections before listeners in the radix test cleanup

A connection's assist thread reads from its network BIO, which for a
dgram BIO pair belongs to the linked listener. Freeing a listener while
the connection's assist thread is still running is a use-after-free.
Freeing connections first joins their assist threads, so no thread is
reading when the listener BIOs are freed.

Fixes #32420
