[PATCH] nl80211: Add support to disable CCK rate for p2p probe and frames

Add a new attribute to specify whether to use CCK rate or not during
scan and sending management frames. This helps to send p2p probes
at non-CCK rate. This ensures that P2P probe request/response/action
frames are awlays sent at non CCK rates.
