ls-tree: rename "retval" to "recurse" in "show_tree()" 

The variable which "show_tree()" return is named "retval", a name that's
a little hard to understand. The commit rename "retval" to "recurse"
which is a more meaningful name than before in the context. We do not
need to take a look at "read_tree_at()" in "tree.c" to make sure what
does "retval" mean.
