[libvirt] [PATCH] qemu-ns: Detect /dev/* mount point duplicates even better
In 4f1570720218302 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 but possible.
