RDMA/ocrdma: Convert kernel VA to PA for mmap in user
In some platforms, when iommu is enabled, the bus address returned by
dma_alloc_coherent is different than the physical address. ocrdma
should use physical address for mmap-ing the queue memory for the
applications.
This patch adds the use of virt_to_phys() at all such places where
kernel buffer is mapped to user process context.
