[Crash-utility] [PATCH 1/2] Exclude NULL entries from do_maple_tree() return value

From: Kazuhito Hagio <k-hagio-ab(a)nec.com&gt; While the return value of do_radix_tree() and do_xarray() does not contain NULL entries, do_maple_tree()'s one contains NULL entries. Make this behavior consistent with the previous tree functions to make replacement easier, especially for the following patch.
