[Make-wifi-fast] [PATCH] ath10k: Re-enable TXQs for all devices

["Toke Høiland-Jørgensen" <toke@toke.dk>]

Commit 4ca1807815aa6801aaced7fdefa9edacc2521767 disables the use of the
mac80211 TXQs for some devices because of a theoretical throughput
regression. We have not seen this regression for a while now, so it
should be safe to re-enable TXQs.

This has been in LEDE trunk for a couple of months now with good results.
