Assuming sums of values stored in variables such as sub_total_cnt
and total_ppdu_cnt are big enough to warrant their u64 type, it
makes sense to ensure that their calculation takes into account
possible integer overflow issues.

Play it safe and fix the problem by casting right hand expressions
to u64 as well. Also, slightly adjust tabulation.

2d5630b0c9 wifi: mt76: mt7925: fix fails to enter low power mode in suspend state 
The mt7925 sometimes fails to enter low power mode during suspend.
This is caused by the chip firmware sending an additional ACK event
to the host after processing the suspend command. Due to timing issues,
this event may not reach the host, causing the chip to get stuck.
To resolve this, the ACK flag in the suspend command is removed,
as it is not needed in the MT7925 architecture. This prevents the
firmware from sending the additional ACK event, ensuring the device
can reliably enter low power mode during suspend.
