qcow2: Handle full/falloc preallocation in qcow2_co_create()

Once qcow2_co_create() can be called directly on an already existing
node, we must provide the 'full' and 'falloc' preallocation modes
outside of creating the image on the protocol layer. Fortunately, we
have preallocated truncate now which can provide this functionality.
