Please keep the Free() function closer to the Alloc() function.

The function names are inconsistent here: they all deal with hash
keys, but only the free function contains the word "key" in its
name.
Please change them like so:
virZPCIAddrCode() => virZPCIAddrKeyCode()
virZPCIAddrEqual() => virZPCIAddrKeyEqual()
virZPCIAddrCopy() => virZPCIAddrKeyCopy()

This hunk is a leftover from a previous respin, please drop it.

Hm. Instead of exporting this function just so you can call it from
qemuDomainPCIAddressSetCreate(), wouldn't it make more sense to call
it directly from inside virDomainPCIAddressSetAlloc()?
You'd have to pass virPCIDeviceAddressExtensionFlags to the latter,
of course, but that sounds fairly sensible; the only other user,
the bhyve driver, can just pass _NONE.

This should be
if (... &&
virDomainPCIAddressSetExtensionAlloc(...) < 0) {
...
