mds: pick_inode_snap should consider follows==0 valid

I suspect a larger audit of 'follows' semantics may be necessary..
but this fixes the bug I was seeing with:

echo asdf > a
mkdir .snap/1
echo qwer > b
mkdir .snap/2
echo zxcv > a
mkdir .snap/3
sync
cat .snap/1/a   # empty
ll .snap/*      # hangs
