[PATCH 2/2] maple_tree: fix comment typo with corresponding maple_status

[Wei Yang <richard.weiyang@gmail.com>]

In comment of function mas_start(), we list the return value of
different cases. According to the comment context, tell the maple_status
here is more consistent with others.

Let's correct it with ma_active in the case it's a tree.
