[PATCH] ieee80211: Provide generic get_stats implementation

bcm43xx and ipw2100 currently duplicate the same simplistic get_stats
handler.  Additionally, zd1211rw requires the same handler to fix a
bug where all stats are reported as 0.

This patch adds a generic implementation to the ieee80211 layer,
which drivers are free to override.
