Prevent a double free by not reentering be_tls_close().
Reentering this function with the right timing caused a double free,
typically crashing the backend. By synchronizing a disconnection with
the authentication timeout, an unauthenticated attacker could achieve
this somewhat consistently. Call be_tls_close() solely from within
proc_exit_prepare(). Back-patch to 9.0 (all supported versions).
