We look up the fs root in various places in here when recovering from a
crashed relcoation. Make sure we hold a ref on the root whenever we
look them up.

Please drop this patch from all stable versions. It's part of a
larger series that is preparatory switching from SRCU to refcounts, so
the patch on itself does not fix anything.

I've dropped it, thanks!
