f2fs: fix a bug when using namehash to locate dentry bucket
In the following scenario,
1) we don't have the key and doing a lookup for encrypted file,
2) and the encrypted filename is big name
we should use fname->hash as name hash value instead of what is
calculated by fname->disk_name. Because in such case,
fname->disk_name is empty.
