ubifs: dbg_orphan_check: Fix missed key type checking
When selinux/encryption is enabled, xattr entry node is added into TNC
before host inode when creating new file. So it is possible to find
xattr entry without host inode from TNC. Orphan debug checking is called
by ubifs_orphan_end_commit(), at that time, the commit semaphore is
already unlock, so the new creation won't be blocked.
Fixes: d7f0b70d30ff ("UBIFS: Add security.* XATTR support for the UBIFS")
Fixes: d475a507457b ("ubifs: Add skeleton for fscrypto")
