Avoid making /dev/bmm

Modern systems use udev to manage /dev, and so /dev/bmm should be
already created.

Nevertheless, having a library try to create a device node is insane;
the library doesn't know what context it is being called from.  Neither
should it try to create device nodes as non-root users.

Get rid of this code.
