description:
since we're now attached the [bc]devsw's, grabbing the assigned majors,
and then detaching (in anticipation of the driver module doing its own
attach), we need to make sure that the driver name matches what is
expected in devsw_attach().  In particular, the driver name is "cgd"
and not "/dev/cgd0"  :)

While here, we might as well record the major numbers from the first
call, and just reuse them later.  So make the module's variables global,
and reference them in the rump initialization code.

Yay - cgd now works in the localcount world, both as a kernel module
and as a rump component.
