[pve-devel] [PATCH qemu-server] fix #5543: pci: don't use pci devices when starting templates

templates can only be started in context of a pbs backup, and there
we don't need or want to use the configured pci devices, since
they cannot be started normally anyway.
Without this, users can get into a situation where the template
cannot be backed up when the pci device is not available, even
if it's actually not needed.
