xfs: use hlist_add_fake
XFS does not need it's inodes to actuall be hashed in the VFS inode cache, but we require the inode to be marked hashed for the writeback code to work. Insted of using insert_inode_hash, which requires a second inode_lock roundtrip after the partial merge of the inode scalability patches in 2.6.37-rc simply use the new hlist_add_fake helper to mark it hashed without requiring a lock or touching a global cache line.
