ice: remove filters only if VSI is deleted

Filters shouldn't be removed in VSI rebuild path. Removing them on PF
VSI results in no rule for PF MAC after changing for example queues
amount.

Remove all filters only in the VSI remove flow. As unload should also
cause the filter to be removed introduce, a new function ice_stop_eth().
It will unroll ice_start_eth(), so remove filters and close VSI.
