wifi: mt76: mt7996: set correct wcid in txp
[ Upstream commit bde2e77f76266fbd81ff74cb12b3d87f9460b1e0 ]
Set correct wcid in txp to let the SDO hw module look into the correct
wtbl, otherwise the tx descriptor may be wrongly fiiled. This patch also
fixed the issue that driver could not correctly report sta statistics,
especially in WDS mode, which misled AQL.
