target/arm: Set ARMMMUFaultInfo.level in user-only arm_cpu_tlb_fill
Pretend the fault always happens at page table level 3.
Failure to set this leaves level = 0, which is impossible for
ARMFault_Permission, and produces an invalid syndrome, which
reaches g_assert_not_reached in cpu_loop.
Fixes: 8db94ab4e5db ("linux-user/aarch64: Pass syndrome to EXC_*_ABORT")
