[PATCH revision 2] windfarm: dont die on suspend thread signal

[Johannes Berg]

When the windfarm thread gets a suspend signal it will die instead of
freezing. This fixes it.

Adresses Christoph's comment: This keeps the original try_to_freeze() in
place and just remove the code that kills the thread on a signal.
