[PATCH 1/3] wifi: mt76: usb: create a dedicated queue for psd traffic

[Deren Wu <deren.wu@xxxxxxxxxxxx>]

From: Lorenzo Bianconi <lorenzo@xxxxxxxxxx>

Create a dedicate queue for psd/mgmt traffic and do not rely on voice
one. This is a preliminary patch to fix mt7921u/mt7925 usb dmasl
configuration.
