Zhihao Cheng b2dd05f107 ovl: let helper ovl_i_path_real() return the realinode 
Let helper ovl_i_path_real() return the realinode to prepare for
checking non-null realinode in RCU walking path.

[msz] Use d_inode_rcu() since we are depending on the consitency
between dentry and inode being non-NULL in an RCU setting.
