5a6809590c Bug #46080: group_concat(... order by) crashes server when 
sort_buffer_size cannot allocate

The NULL return from tree_insert() (on low memory) was not
checked for in Item_func_group_concat::add(). As a result
on low memory conditions a crash happens.

Fixed by properly checking the return code.
