From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit 7a836a2aba09479c8e71fa43249eecc4af945f61 ]
If an error occurs after a successful pci_request_selected_regions() call,
it should be undone by a corresponding pci_release_selected_regions() call,
as already done in vp_modern_remove().
Fixes: fd502729fbbf ("virtio-pci: introduce modern device module")
