[Impact]
Ath9k stops working after system resume from suspend.
[Fix]
Set sc->rng_task to NULL to avoid further access.
This patch CC'ed stable, so Artful (4.11) will have it in future release.
Only Zesty needs this patch.
[Test Case]
Suspend/resume the system.
Ath9k should no longer freeze.
[Regression Potential]
This patch only effects ath9k, also, the change is pretty small.
The regression potential should be really low.
