arm: Use the mmu_idx we're passed in arm_cpu_do_unaligned_access()
When identifying the DFSR format for an alignment fault, use the mmu index that we are passed, rather than calling cpu_mmu_index() to get the mmu index for the current CPU state. This doesn't actually make any difference since the only cases where the current MMU index differs from the index used for the load are the "unprivileged load/store" instructions, and in that case the mmu index may differ but the translation regime is the same (apart from the "use from Hyp mode" case which is UNPREDICTABLE). However it's the more logical thing to do.
