When per-packet rate reporting is enabled, the hardware can get stuck under
some conditions. It self-recovers quickly, but in practice this leads to
reduced performance.
In order to avoid running into this issue, disable per-packet rate reporting
by default and query the rx rate from firmware instead, unless monitor mode
is enabled.

Signed-off-by: Felix Fietkau <nbd@nbd.name>

In the MT7915 info, the fields for the WLAN index / queue overlap with the
token id, and the MT_TX_FREE_PAIR bit indicates, which one is present.

If MT_TX_FREE_PAIR is set, skip processing the token index, since the data
will not be valid.

This fixes accidentally freeing tokens which are still in use by the
hardware with a wrong station pointer.

When looking for a MAC address slot, start by using main BSSID slots 1-3,
afterwards use 16 repeater mode BSSID slots, then start using the slots
