Wei Fu 34672d483d metadata/gc: remove the noop-loop for snapshot reference ...

The noop-loop does nothing.

The containerd doesn't have any snapshotter buckets at the beginning.
If user uses specific dir as rootfs to create container, and sets
`snapshotter` key to the container, like `overlayfs` by mistake,
the gc scheduler will try to scan the snapshotter and panic.

In order to avoid this case, remove the noop-loop here.
