Fix issue in receive_object() during reallocation

When receiving an object to a previously allocated interior slot
the new object should be "allocated" by setting DMU_NEW_OBJECT,
not "reallocated" with dnode_reallocate().  For resilience verify
the slot is free as required in case the stream is malformed.

Add a test case to generate more realistic incremental send streams
that force reallocation to occur during the receive.
