Subject: [PATCH 5.15 421/913] mt76: connac: fix sta_rec_wtbl tag len

From: Lorenzo Bianconi <lorenzo@...nel.org>

[ Upstream commit 74c337ec0905d99111fc63a15f2e0784b9ed5503 ]

Similar to mt7915 driver, fix tag len error for sta_rec_wtbl, which
causes fw parsing error for the tags placed behind it.
