Fixed some memory leaks in divelist.c related to gtk_tree_iter_copy()

Browse source 
divelist.c:
get_iter_from_idx() goes trought the tree model and calls
iter_has_index(), until a match is found. when the match is found
we use gtk_tree_iter_copy() to make a copy of the iterator.

This means that the caller of get_iter_from_idx() has to take care
the de-allocation using gtk_tree_iter_free().

Also take care of the eventual:
parent = gtk_tree_iter_copy(...)
allocation in select_prev_dive(), select_next_dive()
