[PATCH v2 3/3] wifi: ath12k: Refactor error handler of Rxdma replenish

[Karthikeyan Periyasamy <quic_periyasa@quicinc.com>]

The Rxdma replenish handler currently contains redundant code in both the
success and error cases. To avoid the redundant code, implement a
conditional jump mechanism by placing a goto statement to prevent
unnecessary execution of the error handling code when the operation is
successful. This change streamline the code readability and enhance its
efficiency.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
