mac80211: use DECLARE_EWMA for ave_beacon_signal
It doesn't seem problematic to change the weight for the average beacon signal from 3 to 4, so use DECLARE_EWMA. This also makes the code easier to maintain since bugs like the one fixed in the previous patch can't happen as easily. With a fix from Avraham Stern to invert the sign since EMWA uses unsigned values only. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
