powerpc/booke:  Only handle kernel page faults in KVA range

The memory range between VM_MAXUSER_ADDRESS and VM_MIN_KERNEL_ADDRESS is
reserved for devices currently, which are always mapped in TLB1, and
therefore do not exist in the kernel page table.  Any page fault in this
range is therefore automatically a fatal fault.
