[PATCH] wl12xx: configure rates when working in ibss mode

[Eliad Peller <eliad@wizery.com>]

When working in ibss mode, we don't configure rate policy per station
(as we use the same link for multiple stations), so currently the
1mb/s rate is being used.

Instead, configure the firmware to use the whole 11b rates by default.
