[pve-devel] [PATCH container] fix #1851: check 'replicate' flag for non-volume mountpoints

[Dominik Csapak]

setting replicate=0 for a bind mount only makes sense if we
really skip it for replication

also cleanup for them is not necessary, as bind mounts
could not have ever been replicated, thus there should
not be anything to clean up
