wifi: ath12k: change MAC buffer ring size to 4096
For WCN7850, MAC buffer ring size is updated to 2048 in
955df16f2a4c3 ("wifi: ath12k: change MAC buffer ring size to 2048")
to increase peak throughput.
But during the RX process, a phenomenon can still be observed where
the throughput drops by about 30% from its peak value and then recovers,
and this behavior repeats during RX.
After increasing MAC buffer ring size to 4096, the data rate drop has
gone.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3
