Trying to 'zfs diff' a snapshot with large dnodes will incorrectly try to access its interior slots when dnodesize > sizeof(dnode_phys_t). This is normally not an issue because the interior slots are zero-filled, which report_dnode() handles calling report_free_dnode_range(). However this is not the case for encrypted large dnodes or filesystem using many SA based xattrs where the extra data past the legacy dnode size boundary is interpreted as a dnode_phys_t.
