x86/amd_gart: return error code from gart_map_sg()
The .map_sg() op now expects an error code instead of zero on failure.
So make __dma_map_cont() return a valid errno (which is then propagated
to gart_map_sg() via dma_map_cont()) and return it in case of failure.
Also, return -EINVAL in case of invalid nents.
