[PATCH-for-5.0 v3 3/6] hw/pci-host/i440fx: Use size_t to iterate over ARRAY_SIZE()

[Philippe Mathieu-Daudé]

We don't enforce the -Wsign-conversion CPPFLAG, but it doesn't hurt
to avoid this warning:

  warning: implicit conversion changes signedness: 'int' to 'size_t' (aka 
'unsigned long') [-Wsign-conversion]
