mm/writeback: minor clean up for highmem_dirtyable_memory
Since commit a804552b9a15 ("mm/page-writeback.c: fix dirty_balance_reserve subtraction from dirtyable memory"), local variable x can not be negative. And it can not overflow when it is the total number of dirtyable highmem pages. Thus remove the unneeded comment and overflow check.
