There is a bug in ieee80211softmac that always sets the user rate to 11Mbs,
no matter the capabilities of the device. This bug was probably beneficial
as long as the bcm43xx cards were rate limited; however, most are now capable
of relatively high speeds. This patch fixes that bug and eliminates an assert
that is no longer needed.
Once the cards are capable of full OFDM speeds, the 24 Mbs rate will be changed
to 54 Mbs.
