kernel: fix Mediatek queue size patch

This got added in commit 15887235, cherry-picked into the 24.10 branch
as 642b5b61 and was partially lost in a manual patch refresh in
3a2a2c99.

The main branch still contains the full set of rx DMA size changes, so I
assume it was lost by accident.

With rx.dma_size=2K, my TP-Link Archer MR600v2 (MT7621) randomly reboots
due to OOM.
