> are set in the pf->state, the most intrusive one is meant to be performed
> only, but the bits requesting the other types are not being cleared. This

> Change the flow of ice_reset_subtask so that all reset request bits in
> pf->state are cleared, and we still perform the most intrusive of the
> resets requested.
