iavf: fix reset task race with iavf_remove()
The reset task is currently scheduled from the watchdog or adminq tasks.
First, all direct calls to schedule the reset task are replaced with the
iavf_schedule_reset(), which is modified to accept the flag showing the
type of reset.
To prevent the reset task from starting once iavf_remove() starts, we need
to check the __IAVF_IN_REMOVE_TASK bit before we schedule it. This is now
easily added to iavf_schedule_reset().
Finally, remove the check for IAVF_FLAG_RESET_NEEDED in the watchdog task.
It is redundant since all callers who set the flag immediately schedules
the reset task.
Fixes: 3ccd54ef44eb ("iavf: Fix init state closure on remove")
Fixes: 14756b2ae265 ("iavf: Fix __IAVF_RESETTING state usage")
