Fix encryption root hierarchy issue

After doing a recursive raw receive, zfs userspace performs a final pass to adjust the encryption root hierarchy as needed. Unfortunately, the FORCE_INHERIT ioctl had a bug which caused the encryption root to always be assigned to the direct parent instead of the inheriting parent. This patch simply fixes this issue.
