wifi: rtw88: Fix rtw_desc_to_mcsrate() to handle MCS16-31

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.
