xen/netfront: fix waiting for xenbus state change
commit 8edfe2e992b75aee3da9316e9697c531194c2f53 upstream.
Commit 822fb18a82aba ("xen-netfront: wait xenbus state change when load
module manually") added a new wait queue to wait on for a state change
when the module is loaded manually. Unfortunately there is no wakeup
anywhere to stop that waiting.
Instead of introducing a new wait queue rename the existing
module_unload_q to module_wq and use it for both purposes (loading and
unloading).
As any state change of the backend might be intended to stop waiting
do the wake_up_all() in any case when netback_changed() is called.
Fixes: 822fb18a82aba ("xen-netfront: wait xenbus state change when load module manually")
