sparc64: flush translations on mmu context change

- two pairs of softmmu indexes bind softmmu tlb to cpu tlb in fault handlers
using value of DMMU primary and secondary context registers, so we need to
flush softmmu translations when context registers are changed...

sparc64: fix mmu context at trap levels above zero

- cpu_mmu_index return MMU_NUCLEUS_IDX if trap level is not zero
- cpu_get_tb_cpu_state: store trap level and primary context in flags
this allows to restart code translation when address translation is changed...
