Richard Henderson b9bed1b9ab target/openrisc: Fix cpu_mmu_index
The code in cpu_mmu_index does not properly honor SR_DME.
This bug has workarounds elsewhere in that we flush the
tlb more often than necessary, on the state changes that
should be reflected in a change of mmu_index.

Fixing this means that we can respect the mmu_index that
is given to tlb_flush.
