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.
