Change this so we can use more information about the station to use a better rate. For example, when we associate with an AP, we will now use the lowest rate it advertised as supported (that we can) rather than the lowest mandatory rate. This aligns our behaviour with most other 802.11 implementations. To make this possible, we need to also ensure that we have non-zero rates at all times, so in case we really have *nothing* pre-fill the supp_rates bitmap with the very lowest mandatory bitmap (11b and 11a on 2.4 and 5 GHz respectively). Additionally, hostapd appears to be giving us an empty supported rates bitmap (it can and should do better, since the STA must have supported for at least the basic rates in the BSS), so ignore any such bitmaps that would actually zero out the supp_rates, and in that case just keep the pre-filled mandatory rates.
