[PATCH 1/2] ath10k: Fix rate table updation in tx stats

[Rakesh Pillai <pillair@codeaurora.org>]

The index for updating rate table, which is displayed
in the tx stats via debugfs, is calculated using the
bandwidth value. The bandwidth values do not map
correctly with the bandwidth values shown in the rate table.

Correct the bandwidth value calculation which is used
to calculate the index for rate table updation for tx stats.

Tested HW: WCN3990
Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1

Fixes: e88975ca37d1 ("ath10k: dump tx stats in rate table format")
