target/mips: Use correct MMU index in get_pte()
When refactoring page_table_walk_refill() in commit 4e999bf419
we missed the indirect call to cpu_mmu_index() in get_pte():
page_table_walk_refill()
-> get_pte()
-> cpu_ld[lq]_code()
-> cpu_mmu_index()
Since we don't mask anymore the modes in hflags, cpu_mmu_index()
can return UM or SM, while we only expect KM or ERL.
Fix by propagating ptw_mmu_idx to get_pte(), and use the
cpu_ld/st_code_mmu() API with the correct MemOpIdx.
