Bug description:
If ecryptfs_encrypted_view or ecryptfs_xattr_metadata is being specified as mount options, a NULL pointer dereference is possible during lookup.

Reproduce:
---
# mount -t ecryptfs lower upper 
# touch upper/oops
# umout upper
# mount -t ecryptfs lower upper -o ecryptfs_encrypted_view
# ls upper/
---

You should have seen an oops after running `ls`.
