target-ppc: Fix page table lookup with kvm enabled

With kvm enabled, we store the hash page table information in the hypervisor.
Use ioctl to read the htab contents. Without this we get the below error when
trying to read the guest address

 (gdb) x/10 do_fork
 0xc000000000098660 <do_fork>:   Cannot access memory at address 0xc000000000098660
 (gdb)
