RDMA/cxgb4: use dma_mmap_coherent() for mapping non-contiguous memory
dma_alloc_coherent() allocates contiguous memory irrespective of
iommu mode, but after commit f5ff79fddf0e ("dma-mapping: remove CONFIG_DMA_REMAP")
if iommu is enabled in translate mode, dma_alloc_coherent() may
allocate non-contiguous memory. Attempt to map this memory results in panic.
This patch fixes the issue by using dma_mmap_coherent() to map each page
to user space.
