[PATCH] delete obsolete function btrfs_print_tree()

[Holger Hoffstätte]

Dan Carpenter's static checker recently found missing IS_ERR handling
in print-tree.c:btrfs_print_tree(). While looking into this I found that
this function is no longer called anywhere and was moved to btrfs-progs
long ago. It can simply be removed.
