  sheep: Only ledger and inode objects keep sparse when "dog node md plug"

>From the commit 2e3e1ee, atomic_create_and_write have required the sparse
parameter and md_move_object have called this with sparse=true. Because of
this, *all* the objects moving across the disks become sparse when
"dog node md plug," including the ones which should not become sparse
such as pre-allocated fully-zeroed data objects.

This commit fixes the problem described above. To be specific, before
calling atomic_create_and_write, md_move_object calls is_sparse_object
to check whether the given object can be sparse i.e. is either ledger or
inode object.
