[PATCH] tree-walk: use enum interesting instead of integer

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Commit d688cf0 (tree_entry_interesting(): give meaningful names to
return values - 2011-10-24) converts most of the tree_entry_interesting
values to the new enum, except "never_interesting". This completes the
conversion.
