arm/arm64: KVM: Report correct FSC for unsupported fault types
When we catch something that's not a permission fault or a translation fault, we log the unsupported FSC in the kernel log, but we were masking off the bottom bits of the FSC which was not very helpful. Also correctly report the FSC for data and instruction faults rather than telling people it was a DFCS, which doesn't exist in the ARM ARM.
