minstrel: make the rate control ops reusable from another rc implementation

Browse Source 
This patch makes it possible to reuse the minstrel rate control ops
from another rate control module. This is useful in preparing for the
new 802.11n implementation of minstrel, which will reuse the old code
for legacy stations.
