Subject: [PATCH 5.12 13/48] mt76: mt7921: fix max aggregation subframes setting

From: Felix Fietkau <nbd@....name>

[ Upstream commit 94bb18b03d43f32e9440e8e350b7f533137c40f6 ]

The hardware can only handle 64 subframes in rx direction and 128 for tx.
Improves throughput with APs that can handle more than that
