wifi: ath12k: avoid explicit HW conversion argument in Rxdma replenish

Currently Rxdma replenish require HW conversion argument which is
unnecessary argument since ath12k driver configures the Rxdma only
in HW conversion. To optimize the rx data path per packet, avoid
the explicit unnecessary argument and condition check in the rx
replenish.
