btrfs-progs: Fix 2 extent buffer leak in btrfs-debug-tree

Browse Source 
There are 2 known extent buffer leaks:
1) With -t option.
-t option will skip other tree roots, but it will read the root node
first and then skip it.
Where it forgets to free the tree block it read.

2) with -b option.
It forgets to free the tree block it read.
