Subject: [PATCH 5.18 086/181] ice: Fix switchdev rules book keeping

From: Wojciech Drewek <wojciech.drewek@...el.com>

[ Upstream commit 3578dc90013b1fa20da996cdadd8515802716132 ]

Adding two filters with same matching criteria ends up with
one rule in hardware with act = ICE_FWD_TO_VSI_LIST.
In order to remove them properly we have to keep the
information about vsi handle which is used in VSI bitmap
(ice_adv_fltr_mgmt_list_entry::vsi_list_info::vsi_map).

Fixes: 0d08a441fb1a ("ice: ndo_setup_tc implementation for PF")
