Vivek Goyal a357665097 devmapper: Make sure device is a thin pool device ...

Right now we check for the existence of device but don't make sure it is
a thin pool device. We assume it is a thin pool device and call poolStatus()
on the device which returns an error EOF. And that error does not tell
anything.

So before we reach the stage of calling poolStatus() make sure we are working
with a thin pool device otherwise error out.
