i40evf: cancel workqueue sync for adminq when a VF is removed
If a VF is being removed, there is no need to continue with the
workqueue sync for the adminq task, thus cancel it. Without this call,
when VFs are created and removed right away, there might be a chance for
the driver to crash with events stuck in the adminq.
