Miklos Szeredi a6f15d9a75 ovl: don't traverse automount points
NFS and other distributed filesystems may place automount points in the
tree.  Previoulsy overlayfs refused to mount such filesystems types (based
on the existence of the .d_automount callback), even if the actual export
didn't have any automount points.

It cannot be determined in advance whether the filesystem has automount
points or not.  The solution is to allow fs with .d_automount but refuse to
traverse any automount points encountered.
