The commit b5fd8b18335f2a7784a1f0a5eb5dbe45976d9e21
"VHT: Do not allow use of TKIP with VHT" introduced
an off-by-one regression: a WPA/RSN 11n ap would no
longer accept stations to connect, instead it would
produce a bogus error message:
... Station tried to use TKIP with HT association.

This time, I got the right commit-id (the one which
broke the code) and just for good measure: a reworded
commit message.
