[PATCH] ieee80211softmac: Fix setting of initial transmit rates

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.
