nfs: use file_dentry()
NFS may be used as lower layer of overlayfs and accessing f_path.dentry can
lead to a crash.
Fix by replacing direct access of file->f_path.dentry with the
file_dentry() accessor, which will always return a native object.
Fixes: 4bacc9c9234c ("overlayfs: Make f_path always point to the overlay and f_inode to the underlay")
