mm: page_owner: fix wrong information in dump_page_owner
With commit ea4b5b33bf8a ("mm,page_owner: update metadata for tail
pages"), new API __update_page_owner_handle was introduced and arguemnt
was passed in wrong order from __set_page_owner and thus page_owner is
giving wrong data.
[ 15.982420] page last allocated via order 0, migratetype Unmovable, gfp_mask 0xcc0(GFP_KERNEL), pid 80, tgid -1210279584 (insmod), ts 80, free_ts 0
Fixing the same.
Correct output:
[ 14.556482] page last allocated via order 0, migratetype Unmovable, gfp_mask 0xcc0(GFP_KERNEL), pid 80, tgid 80 (insmod), ts 14552004992, free_ts 0
