4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Malcolm Priestley <tvboxspy@xxxxxxxxx>
commit cc26358f89c3e493b54766b1ca56cfc6b14db78a upstream.
A check for vif is made in vnt_interrupt_work.
There is a small chance of leaving interrupt disabled while vif
is NULL and the work hasn't been scheduled.
