f2fs: kill dead code in __insert_extent_tree
After commit 0f825ee6e873 ("f2fs: add new interfaces for extent tree"),
f2fs_init_extent_tree becomes the only caller of __insert_extent_tree, and
in f2fs_init_extent_tree, we will only insert extent node in an empty tree,
so __try_{back,front}_merge in __insert_extent_tree will never be called.
This patch removes these dead codes, besides, rename __insert_extent_tree
to __init_extent_tree for readability.
