ath9k: Fix incorrect user ratekbs of MCS15 ShortGI
The user ratekbs of MCS15 ShortGI is incorrect and can not be lesser than MCS15 rate. This incorrect rate may affect switching to higher rates as the rate control algorithm always finds MCS15 is better than MCS15 ShortGI and results in lower throughput. Fix this by feeding the correct user ratekbs for MCS15 ShortGI rate. This issue affects 3 stream case very badly as the 3 stream rates are not used at all once we scale down to MCS15 from 3 stream rates.
