Currently, number of available tx retry policies is checked two times.
Only one is sufficient.

This warning is more clear than the original which is good, but that's
not what the commit message says.  How does this fix a double warning?

Err... Indeed, it don't. From wfx_tx_get_rate_id():

       rate_id = wfx_tx_policy_get(wvif, ...);
       if (rate_id == WFX_INVALID_RATE_ID)
               dev_warn(wvif->wdev->dev, "unable to get a valid Tx policy");

I will fix that in my next PR.
