d80211/bcm43xx: Modify struct ieee80211_local for wireless statistics.

Part 2 of 8 to add wireless statistics to the bcm43xx-d80211 system. This patch adds new variables to struct ieee80211_local to contain the link_quality and noise. These could be u8's for bcm43xx, but have been left as int's in case other drivers need a larger range.

The patch is for the August 8 version of Linville's wireless-dev tree.
