Subject: [PATCH net 3/6] iavf: simplify watchdog_task in terms of adminq task scheduling

From: Przemek Kitszel <przemyslaw.kitszel@...el.com>

Simplify the decision whether to schedule adminq task. The condition is
the same, but it is executed in more scenarios.

Note that movement of watchdog_done label makes this commit a bit
surprising. (Hence not squashing it to anything bigger).
