This function translates the rate number reported by the hardware into
something mac80211 can understand. It was ignoring the 3SS and 4SS HT
rates. Translate them too.

Also set *nss to 0 for the HT rates, just to make sure it's
initialised.

v2:
 - Set *nss for the HT rates.

v3:
 - Set *nss before *mcs.
