qemu-ns: Detect /dev/* mount point duplicates even better

Browse Source 
In 4f15707202 I've tried to make duplicates detection for
nested /dev mount better. However, I've missed the obvious case
when there are two same mount points. For instance if:

  # mount --bind /dev/blah /dev/blah
  # mount --bind /dev/blah /dev/blah

Yeah, very unlikely (in qemu driver world) but possible.
