Use two 32-bit writes instead of a single 64-bit write to write the
message address into an MSI-X table entry. The RTL8168/RTL8111 hardware
does not respond to 64-bit access (reads return all-ones, writes are
ignored) and the PCI specification documents separate 32-bit "DWORD"
fields for message address and message upper address.
