The only case where we actually need to perform a dcache maintenance

faults do not require cache maintenance. Let's make it conditional

This patch unfortunately breaks something on Hi1616 SoCs when running
32bit guests. With this patch applied (and thus with 4.18) I get random
illegal instruction warnings from 32bit code inside VMs. I do not know
at this point whether this affects other CPUs as well.
If anyone is interested in a reproducer, I have something handy. But for
now I believe we should just revert this patch.
