volumes: fix error-handling when removing volumes with swarm enabled
Commit 3246db3755 added handling for removing
cluster volumes, but in some conditions, this resulted in errors not being
returned if the volume was in use;

    docker swarm init
    docker volume create foo
    docker create -v foo:/foo busybox top
    docker volume rm foo

This patch changes the logic for ignoring "local" volume errors if swarm
is enabled (and cluster volumes supported).

While working on this fix, I also discovered that Cluster.RemoveVolume()
did not handle the "force" option correctly; while swarm correctly handled
these, the cluster backend performs a lookup of the volume first (to obtain
its ID), which would fail if the volume didn't exist.

Before this patch:
