i40evf: fix oops in watchdog handler

Browse source

The Tx watchdog handler runs in interrupt context, so it would cause an
oops when sending an admin queue message to request a reset, because the
admin queue functions use spinlocks.

Instead, set a flag and let the reset task handle sending the request.
