sparc/iommu: return error codes from .map_sg() ops

Browse source

The .map_sg() op now expects an error code instead of zero on failure.

Returning an errno from __sbus_iommu_map_sg() results in
sbus_iommu_map_sg_gflush() and sbus_iommu_map_sg_pflush() returning an
errno, as those functions are wrappers around __sbus_iommu_map_sg().
