Vivek Goyal a3ad44f760 devmapper: Provide a helper function getNextDeviceId() ...

Right now we are accessing devices.NextDeviceId directly and also 
incrementing it at various places.

Instead provide a helper function which is responsile for
incrementing NextDeviceId and return next deviceId. 

This is just code structuring. This will help later once we
convert this function to find a free device Id and it goes
through a bitmap of used/free device Ids.
