After this commit getdevice() from pciconf(8) and pci_find_conf() in
tools/tools/dmardump/dmardump.c always fail in EPERM in -m32 mode.
Found via graphics/libdrm where PCIOCGETCONF is used to get a list of
DRM devices for use by OpenGL/Vulkan/VAAPI userland drivers.
Can you fix the regression before 12.0R or back the commit out?
