[Qemu-ppc] [PATCH] hw/ppc/spapr_iommu: Fix the check for invalid upper bits in liobn |

The check "liobn & 0xFFFFFFFF00000000ULL" in spapr_tce_find_by_liobn()
is completely useless since liobn is only declared as an uint32_t
parameter. Fix this by using target_ulong instead (this is what most
of the callers of this function are using, too).
And while we're at it, change the error message printing into a proper
qemu_log_mask(LOG_GUEST_ERROR, ...) call so that it is also possible
to enable this warning without recompiling the binary.
