ext4: initialize moved_len before calling ext4_move_extents()
The move_extent.moved_len is used to pass back the number of exchanged
blocks count to user space. Currently the caller must clear this
field; but we spend more code space checking for this requirement than
simply zeroing the field ourselves, so let's just make life easier for
everyone all around.
