Subject: [PATCH] block/mq-deadline: Remove the redundant rb_entry_rq in the deadline_from_pos().

From: chengkaitao <chengkaitao@...inos.cn>

In commit(fde02699c242), the "if (blk_rq_is_seq_zoned_write(rq))" was
removed, but the "rb_entry_rq(node)" was inadvertently left behind.
This patch fixed it.
