pnv_ioda_setup_pe_res() calls opal to map a resource with a PE. However,
the code assumes the resource is allocated and it uses the resource
address to find out the segment(s) which need to be mapped to the
PE. In the unlikely case where the resource hasn't been allocated, the
computation for the segment number is garbage, which can lead to
invalid memory access and potentially a kernel crash, such as:

Applied to powerpc/next.
