wcn36xx: Fix warning due to bad rate_idxwcn3680-additions
The rate_idx is the index of the bitrate in the supported rate table.
However the 5Ghz band has a smaller legacy bitrate table than 2.4Ghz
since it does not have the DSSS bitrates (1, 2, 5.5, 11).
So in 5Ghz band the index should adjusted accrodingly (-4).

[bod: Made sure fix is only applied if the rate_idx > n_bitrates]
