fix xen_swiotlb_dma_mmap prototype
xen_swiotlb_dma_mmap was backported from v4.10, but older
kernels before commit 00085f1efa38 ("dma-mapping: use unsigned long
for dma_attrs") use a different signature:
arm/xen/mm.c:202:10: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
.mmap = xen_swiotlb_dma_mmap,
^~~~~~~~~~~~~~~~~~~~
arm/xen/mm.c:202:10: note: (near initialization for 'xen_swiotlb_dma_ops.mmap')
This adapts the patch to the old calling conventions.
Fixes: "swiotlb-xen: implement xen_swiotlb_dma_mmap callback"
