wldev is freed in b43_one_core_detach() and should not be accessed after
that call.  Keep wldev->dev in a local variable.

Linux 3.0 is not affected.  The bug was introduced in 482f0538.

P.S. This needs to be propagated to Linux 3.1.

-	b43_one_core_detach(wldev->dev);
+	b43_one_core_detach(dev);

As a long term solution, we probably want a function that takes wldev 
and has "free" in its name, so that the effect is clear.
