Subject: [PATCH net-next 5/7] ice: remove correct filters during eswitch release

From: Michal Swiatkowski <michal.swiatkowski@...ux.intel.com>

ice_clear_dflt_vsi() is only removing default rule. Both default RX and
TX rule should be removed during release.

If it isn't switching to switchdev, second time results in error, because
TX filter is already there.

Fix it by removing the correct set of rules.

Fixes: 50d62022f455 ("ice: default Tx rule instead of to queue")

It is targetting net-next with fix, because the broken patch isn't yet
in net repo.
