Felix Fietkau 780ea78ba0 wifi: mt76: mt7603: rework/fix rx pse hang check
It turns out that the code in mt7603_rx_pse_busy() does not detect actual
hardware hangs, it only checks for busy conditions in PSE.
A reset should only be performed if these conditions are true and if there
is no rx activity as well.
Reset the counter whenever a rx interrupt occurs. In order to also deal with
a fully loaded CPU that leaves interrupts disabled with continuous NAPI
polling, also check for pending rx interrupts in the function itself.
