Tom Caputi 5dbf8b4edd Fix issues with truncated files in raw sends
This patch fixes a few issues with raw receives involving
truncated files:

* dnode_reallocate() now calls dnode_set_blksz() instead of
  dnode_setdblksz(). This ensures that any remaining dbufs with
  blkid 0 are resized along with their containing dnode upon
  reallocation.

* One of the calls to dmu_free_long_range() in receive_object()
  needs to check that the object it is about to free some contents
  or hasn't been completely removed already by a previous call to
  dmu_free_long_object() in the same function.

* The same call to dmu_free_long_range() in the previous point
  needs to ensure it uses the object's current block size and
  not the new block size. This ensures the blocks of the object
  that are supposed to be freed are completely removed and not
  simply partially zeroed out.

This patch also adds handling for DRR_OBJECT_RANGE records to
dprintf_drr() for debugging purposes.
