Subject: [PATCH 5.7 236/244] ionic: no link check while resetting queues

From: Shannon Nelson <snelson@...sando.io>

commit 3103b6feb4454646558eedc50ece728bc469f341 upstream.

If the driver is busy resetting queues after a change in
MTU or queue parameters, don't bother checking the link,
wait until the next watchdog cycle.

Fixes: 987c0871e8ae ("ionic: check for linkup in watchdog")
