Summary

Migrate to the new encryption key API rather than poking at the
key struct directly.

Notably this driver was very clear about its expectation the net80211
key layout w/ key, TX MIC and RX MIC matches the firmware layout
and just memcpy()'ed it. That has been refactored.

1657	TODO: technically this should be tx/rx mic len calls, but I bet the firmware doesn't support anything other than 8+8 bytes here. (much like I bet everything else.)
1664	TODO: yup, another instance of IEEE80211_KEYBUF_SIZE being used where it really means "128 bit wep/tkip/ccmp key size". I'm going to need to clean this up too.
