    Fix race condition in stop_waiter_thread()

    The signal handler might run before we had a chance to
    set the 'waiter' context to '0', so better do it previously.

Fixing the 1) race condition (introduced).

After all these commits we have other commits simplifying way multipath
signal handlers work that might not be suitable for SRU. Since these
commits are "fixing" this issue during multipath development now I'll
separate wether all these changes are suitable for a SRU for Precise,
Trusty and Utopic.
