[iwm] use rate control info from the node txrates; use mgmtrate for EAPOL frames

This changes the transmit rate control code to do a few things:

* use fixed rates (mcast, ucast, mgmt) where required.
* Don't use a hard-coded 11a or 11bg rate for non-data frames -
  use what net80211 says we should use.
* use mgmtrate for EAPOL frames.
