Alexander Larsson f26203cf54 devmapper: Simplify thin pool device id allocation 
Instead of globally keeping track of the free device ids we just
start from 0 each run and handle EEXIST error and try the next one.

This way we don't need any global state for the device ids, which
means we can read device metadata lazily. This is important for
multi-process use of the backend.

Alexander Larsson 586a511cb5 devmapper: Move error detection to devmapper.go 
This moves the EBUSY detection to devmapper.go, and then returns
a real ErrBusy that deviceset uses.
