also.(Something like the linear page table) But the shadow for L1 table
is not set.

The code path will be shadow_fault -> l1pte_write_fault. Because X is L2
table, so shadow_mark_va_out_of_sync is called , this function will

Also it alloc a L1 shadow for X through shadow_map_l1_into_current_l2.
When allocating, free_out_of_sync_state will be called to free all OO
entry. However, since the OO entry allocated on
shadow_mark_va_out_of_sync has the writable_pl1e to -1, this OO entry
