qcacld-3.0: Fill actual rates if max rates calculation fails

Currently if host driver needs to fill max rates info as part of
get sta stats and if it fails to calculate the max rates info,
it does not fill any rate info and also does not fill other stats
like rssi, because of this user space shows incorrect stats.

To address above issue, fill actual rates info if driver fails to
calculate max rates info and also fill other stats as well.
