The code that uses variable queued has been removed,
and "mt76_is_usb(dev) ? q->ndesc - q->queued : q->queued"
didn't do anything, so all they should be removed as well.
Eliminate the following clang warnings:
drivers/net/wireless/mediatek/mt76/debugfs.c:77:9: warning: variable
‘queued’ set but not used.

Now that AQL works well on all mt76 drivers, completely replace the arbitrary
burst sizing and number of bursts logic for tx scheduling.
For the short period of time in which AQL does not work well yet, limit each
stations to 16 in-flight packets that have no estimated tx time.
This should avoid filling the queue if a station connects and queues up a
large number of packets before rate control information is available, especially
with hardware rate control

Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
for debugfs files.
Semantic patch information:
Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file()
imposes some significant overhead as compared to
DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe().
