Alexander Larsson d2595404a2 devmapper: Move refcounting to DeviceSet ...

We already have some kind of refcounting in DeviceSet, this fleshes
it out to allow it to completely subsume the refcounting in
devmapper.Driver.

This allows us to drop the double refcounting, and the locking inside
devmapper.Driver. This, in particular the locking simplification will
make it easier in the future to parallelize the device mapper.
