[PATCH v5 05/10] xen/domain: Call pci_release_devices() when releasing domain resources

[Oleksandr Andrushchenko <andr2000@gmail.com>]

From: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

This is the very same that we already do for DT devices. Moreover, x86
already calls pci_release_devices().
