hw/ppc/spapr_iommu: Fix the check for invalid upper bits in liobn
PATCH v2 1/1 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).
---
v2:
- Do not change the hcall_dprintf() into a qemu_log_mask() statement.

Thanks. Adjusted for a conflict with Alexey's DDW preliminaries and applied to spapr-next.
