[ 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).
