rt2x00: Fix basic rate initialization
The basic rate which is configured in the register should not match all supported rates, but only the _basic_ rates. Fix this by adding a new flag to the rt2x00_rate structure and whenever the mode is changed, loop over all available rates for that band to get the basic rate mask.
