mac80211: Adds clean sdata helper
Adds hepler to clean sdata ieee80211_clean_sdata similar way as ieee80211_setup_sdata is implemented. The function will be used by other interfaces later. Signed-off-by: Andrei Emeltchenko <andrei.emeltchenko@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
