wifi: mac80211: add RX flag to report radiotap VHT information
mac80211 already reports some basic information in the radiotap header
with the known fields declared by the driver. However, drivers may want
to report more accurate information and in that case the full VHT
radiotap structure needs to be provided.
Add a new RX_FLAG_RADIOTAP_VHT which is set when the VHT information
should be pulled from the skb. Update the code to fill in the VHT fields
to only do so when requested by the driver or if the information has not
yet been set. This way the driver can fully control the information if
it chooses so.
