wifi: ath12k: avoid explicit mac id argument in Rxdma replenish

Currently all Rxdma replenish callers pass zero for the mac id
argument, so make it as zero implicitly. To optimize the rx
data path per packet, avoid the explicit unnecessary argument
in Rxdma replenish function.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00125-QCAHKSWPL_SILICONZ-1
