Subject: [PATCH 6.8 236/715] wifi: mt76: mt7925: fix mcu query command fail

From: Hao Zhang <hao.zhang@...iatek.com>

[ Upstream commit 2f475cb63eb304bdbb58c9b07b0547ca6c343012 ]

Apply query command type properly to make the chip send the response back.
Otherwise, we may see the command timeout in driver side.
