Bug description:
vmd may fail to create sysfs entry while `pci_rescan_bus()` called in
some other drivers like wwan.
This happens after bug 2002089 re-added pci rescan feature back to
wwan t7xx driver to support firmware updates via devlink. t7xx may
call `pci_rescan_bus()` with proper locks, but vmd doesn't.
sysfs: cannot create duplicate filename '/devices/.../resource0'
