Backporting commit 647c2a6cdd for 20.10
When live-restoring a container the volume driver needs be notified that
there is an active mount for the volume.
Before this change the count is zero until the container stops and the
uint64 overflows pretty much making it so the volume can never be
removed until another daemon restart.

Older versions of Go don't format comments, so committing this as
a separate commit, so that we can already make these changes before
we upgrade to Go 1.19.
