x86_cpu_handle_mmu_fault is currently checking twice for writability and executability of pages; the first time to decide whether to trigger a page fault, the second time to compute the "prot" argument to tlb_set_page_with_attrs. Reorganize code so that first "prot" is computed, then it is used to check whether to raise a page fault, then finally PROT_WRITE is removed if the D bit will have to be set.
