Modified Files:
        src/sys/dev/pci: if_iwm.c

Log Message:
Apply OpenBSD if_iwm.c rev.1.148.

> While setting up the basic rate bitmask for iwm's firmware, if the AP does
> not specify basic rates for either the CCK or OFDM set, add just the most
> basic rate to that set (1 Mbit/s in case of CCK, 6 Mbit/s in case of OFDM).
> This behaviour matches what code comments seem to imply.

> The previous code would add all possible basic rates in such cases.
> So if all basic rates were CCK only, the code would add all possible OFDM basic
> rates on top. Then the firmware would send some frames at too high rates, e.g.
> RTS frames would be sent at 24Mbit/s which is a bit risky on noisy channels.
