mm/page_alloc: Drop the deferred printing
For rt kernel, the console printing occurs either atomically or from the printing kthread, all the printk defer functions have been dropped by commit 25f13bd1 ("printk: remove deferred printing"). This patch drops the new one which is introduced by stable commit 0431e132 ("mm/page_alloc: fix potential deadlock on zonelist_update_seq seqlock").
