wifi: ath12k: update the latest CSA counter

At present, the driver configures the firmware to send the Channel Switch
(CS) count event only when the count reaches zero during a Channel Switch
Announcement (CSA). For frames managed by the upper layer, where the driver
does not update the counter, the CS count in these frames remains unchanged
throughout the entire CSA period. This is because the upper layer is not
aware of the latest ongoing count. Indicating same count value throughout
the CSA time is wrong and could lead to connection instabilities.

Fix this by configuring firmware to send CS count event for every count and
then accordingly decrementing the count in mac80211.
