RDMA/irdma: Remove redundant dma_wmb() before writel()

A dma_wmb() is not necessary before a writel() because writel()
already has an even stronger store barrier. A dma_wmb() is only
required to order writes to consistent/DMA memory whereas the
barrier in writel() is specified to order writes to DMA memory as
well as MMIO.
