mac80211: update injection documentation

We don't currently support antenna or rate setting, so remove
that. Also update the link -- the current one is dead and the
wiki can be kept updated easier.

 The injection code can also skip all other currently defined radiotap fields
 facilitating replay of captured radiotap headers directly.
