PCI_DEVICE has overwritten DeviceState::unrealize (pci_qdev_unrealize).
However, LSI53C895A, which is a subclass of PCI_DEVICE, overwrites it
again and doesn't save the parent's implementation so the PCI_DEVICE's
implementation of DeviceState::unrealize will never be called when
unrealize a LSI53C895A device. And it will lead to memory leak and
unplug failure.
For a PCI device, it's better to implement PCIDevice::exit instead of
DeviceState::unrealize. So let's change to use PCIDevice::exit.
Fixes: a8632434c7e9 ("lsi: implement I/O memory space for Memory Move
instructions")
