[RFC] mac80211: add rate to ieee80211_tx_status

[Tomas Winkler <tomas.winkler@intel.com>]

This patch adds rate to ieee80211_tx_status.
Downscaling in iwl4965 is done in FW. Rate scaling algorithm
needs to know at which rate the packet was actually transmitted
Patch 'cfg80211 API for channels/bitrates' removed the placeholder
for this information that was present in ieee80211_tx_control.

This fix or something similar is required for bringing iwlwifi back to life.
Please comments, suggestions 
Thanks
