Currently, the Rxdma buffer replenish procedure implicitly retrieves the number of free entries when the caller passes req_entries as zero. This is helpful to replenishing the Rxdma ring when the caller is unaware of the number of entries to replenish. After the Rxdma ring is initialized, we can pass req_entries as zero to replenish all the free entry in the Rxdma ring. This change helps to align the argument req_entries to the used list entries for better code readability.
