fs: make dedupe work again after a really unfortunate build fix

Browse Source 
In commit 14ce81c08 "fs: get rid of silly base class that causes build
failures now" I neglected to set the dest_count field in the ioctl
arg structure, so bees master hasn't been deduping anything for about
three weeks.

I'd put a THROW_CHECK in here to catch this kind of bug in the future,
but it would be placed at exactly the point where this fix is.
