[patch] fix kvm-userland on ia64

[Jes Sorensen <jes@xxxxxxx>]

Hi,

Patch 6cb7f4d86438f56a5c917ff6148c70bd237ee0e5 introduced an
unconditional call to kvm_arch_do_ioperm() without protecting
with an #ifdef like the remaining calls are.

Cheers,
Jes

Protect calls to kvm_arch_do_ioperm() introduced in
6cb7f4d86438f56a5c917ff6148c70bd237ee0e5 with
#ifdef USE_KVM_DEVICE_ASSIGNMENT similar to how the other calls to
this function are protected.
