Subject: mac80211: give warning if building w/out rate ctrl algorithm

mac80211: give warning if building w/out rate ctrl algorithm

I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack
and drivers w/ no rate control algorithm.  For drivers like RTL8187 that don't
supply their own RC algorithms, this will cause ieee80211_register_hw to
fail (making the driver unusable).

This will tell kconfig to provide a warning if no rate control algorithms
have been selected.  That'll at least warn the user; users that know that
their drivers supply a rate control algorithm can safely ignore the
warning, and those who don't know (or who expect to be using multiple
drivers) can select a default RC algorithm.
