Subject: [PATCH 14/20] staging: wfx: drop struct wfx_grp_addr_table

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

The struct wfx_grp_addr_table is only instantiated on one place. There
is no justifiation for this struct. Moreover, it is not consistent with
other fields related to filtering (filter_bssid, etc...).
