Peter Maydell 9a45b07616 hw/i386/amd_iommu: Don't leak memory in amdvi_update_iotlb() 
In amdvi_update_iotlb() we will only put a new entry in the hash
table if to_cache.perm is not IOMMU_NONE.  However we allocate the
memory for the new AMDVIIOTLBEntry and for the hash table key
regardless.  This means that in the IOMMU_NONE case we will leak the
memory we alloacted.

Move the allocations into the if() to the point where we know we're
going to add the item to the hash table.
