net: aquantia: when cleaning hw cache it should be toggled

Browse source

>From HW specification to correctly reset HW caches (this is a required

be toggled.

It was previosly always just set. Due to the way driver stops HW this
never actually caused any issues, but it still may, so cleaning this up.
