[PATCH] ath10k: fix wmm params per vdev

[Marek Puzyniak]

During wmm tests changing wmm parameters did not change anything.
This was because of mismatch in WMM params per vdev command.
WMM params per vdev uses different command structure than wmm params
per pdev command. Also txop for per vdev settings has the
same units as provided by mac80211.

Patch concerns qca6174.
