btrfs-progs: tree-stats: initialize the key properly

Browse source 
I started hitting a segfault on fuzz test 006 because we couldn't find
the extent root.  This is because the global root search stuff expects
the actual key to be setup properly, not just an objectid.  Fix this by
initializing the key properly so we can find the extent root and other
trees properly.
