Clang's static analyzer claims that dbuf_hold_copy() will have a NULL pointer dereference in data->b_data when called by dbuf_hold_impl(). This is impossible because data is dr->dt.dl.dr_data, which is non-NULL whenever db->db_level == 0, which is always the case whenever dbuf_hold_impl() calls dbuf_hold_copy(). We add an assertion to suppress the complaint.
