BUG/MAJOR: thread/listeners: enable_listener must not call unbind_listener()

unbind_listener() takes the listener lock, which is already held by
enable_listener(). This situation happens when starting with nbproc > 1
with some bind lines limited to a certain process, because in this case
enable_listener() tries to stop unneeded listeners.

This commit introduces __do_unbind_listeners() which must be called with
the lock held, and makes enable_listener() use this one. Given that the
only return code has never been used and that it starts to make the code
more complicated to propagate it before throwing it to the trash, the
function's return type was changed to void.
