[MAC80211]: remove fake set_key() call
Remove adding a fake key with a NONE key algorithm for each
associated STA. If we have hardware with such TX filtering
we should probably extend the sta_table_notification()
callback with the sta information instead; the fact that
it's treated as a key for some atheros hardware shouldn't
bother the stack.
