During the cleanup of the aggregation session, a rx handler (or release timer)
on another CPU might still hold a pointer to the reorder buffer and could
attempt to release some packets.
Clearing pointers during cleanup avoids a theoretical use-after-free bug here.

Before extracting the tid out of the packet, check if it was qos-data.
Only accept tid values 0-7
Also, avoid accepting the hardware queue as skb queue mapping, it could
lead to an overrun. Instead, derive the hardware queue from the tid number,
in order to avoid issues with packets being filtered multiple times.
This also fixes a mismatch between hardware and software queue indexes.

This patch removes a mt76_wr_copy call from the beacon path to hw.
The skb which is used in this place gets therefore build with txwi
inside its data. For mt76 usb drivers, this saves one synchronuous
copy call over usb, which lets the beacon work complete faster.

In mmio case, there is not enough headroom to put the txwi into the
skb, it is therefore using an additional mt76_wr_copy, which is fast
over mmio. Thanks Stanislaw for pointing this out.

Sending beacons to the hardware always happens in batches. In order to
speed up beacon processing on usb devices, this patch splits out common
code an calls it only once.

Beacons are sequentially written into the beacon memory area, by
tracking its usage with the dev->beacon_data_count. For MBSS support
and buffered traffic dev->beacon_data_count is used to create the bypass
mask.

The code is also adapted for the mmio part of the driver, but should not
have any performance implication there.

MBSS tests were performed with AVM AC860 USB NIC with temporary support
for 5 BSS'. Different combinations of active vifs were created and
brought up. Afterwards connection and data transfer was tested for the
announced BSS'.

mt76 hw does not send beacons from beacon slots, if the corresponding
bitmask is set accordingly. Therefore we can omit clearing the beacon
memory. Clearing uses many usb calls, if usb drivers are used. These
calls unnecessarily slow down the beacon tasklet. Thanks to Stanislaw
Gruzska for pointing this out.

Before this patch, mt76 handled rx traffic for all TIDs equally,
when released from reorder buffer early. This patch uses an AC specific
reorder timeout, in order to release partial aggregated frames for video
ACs earlier. Voice ACs are currently not aggregated (thanks to Felix for
this hint). For example, ath10k also uses AC specific reorder timeouts
(reported by firmware in that case).
