Check the count before incrementing it to match vendor code behavior.
This defers the adjustment by one more tick, which should improve accuracy

When mt76x0 and mt76x2 beacon code was unified, it changed the order in which
beacon enable and beacon interval are configured.
Configuring beacon enable before beacon interval can in some cases cause
problems with the beacon timer, leading to clients not waking up properly
from powersave mode.
Fix this by changing the order back to interval first, then enable.

When the timer is already running, there is no need to reset the counter,
because the drift will remain the same.

MCU request timeout usually indicates that the device is no longer responsive,
and it usually does not recover without a reset

ED/CCA needs to be disable before stopping the MAC to avoid hangs from tx
being blocked. It must only be enabled again after the MAC has been started
again.
In many places this wasn't done properly, so fix this by always clearing
the relevant ED/CCA bits in mt76x2_mac_stop and set it up again after
channel change or calibration is done

in mt76x02_edcca_init
