divelist.c:icon_click_cb(): check if a GtkTreePath is found

In icon_click_cb() we need to check if a correct GtkTreePath is found
(using gtk_tree_view_get_path_at_pos()) before requesting a GtkTreeIter
for it.

Without this patch a bug is reproducible, where the user may click
outside of the GtkTreeView entries, but still in the GtkTreeView -
e.g. when only one entry is available.
