[PATCH 5.15 042/148] wifi: mt76: fix reading current per-tid starting sequence number for aggregation

[Greg Kroah-Hartman]

From: Felix Fietkau <nbd@xxxxxxxx>

commit c3a510e2b53785df31d882a773c4c0780b4c825f upstream.

The code was accidentally shifting register values down by tid % 32 instead of
(tid * field_size) % 32.
