commit b7eeb52721fe417730fc5adc5cbeeb5fe349ab26 upstream.
When ice_remove_vsi_lkup_fltr is called, by calling ice_add_to_vsi_fltr_list local copy of vsi filter list is created. If any issues during creation of vsi filter list occurs it up for the caller to free already allocated memory. This patch ensures proper memory deallocation in these cases.
