The race happens when we send ADD_STA(auth->assoc) -> LQ_CMD
between the commands the FW sometimes loses the medium for AUX, and
sends a ndp to the AP and the flow becomes, ADD_STA -> send ndp -> LQ_CMD
the problem is that there's no rates yet defined for sending the ndp and
FW generates an assert.
The fix: change the order of the commands to LQ_CMD -> ADD_STA
