We're currently leaking the resources of the TLS thread by not joining
it and also overwriting the p->thread pointer altogether.
Fixes: a1af605bd5 ("migration/multifd: fix hangup with TLS-Multifd due to blocking
handshake")

This change, which is suggested for -stable, while simple by its own, seems
to depend on the previous changes in this series, which are not for -stable.
In particular, whole "Finally recycle all the threads" loop in
multifd_send_terminate_threads()
(to which the join is being added by this change) is moved from elsewhere by
12808db3b8 "migration/multifd: Cleanup multifd_save_cleanup()" (patch 24 in
this same series).
We can probably add the missing join right into the previous location of this
loop (before 12808db3b8). I did this in the attached variant for 8.2, is
this correct?
And this does not pass even the basic tests, so it's not that simple :)
The following patch (27/34) is more questionable than this one.
Thanks!
