Subject: [PATCH] block: remove duplicate initialization
Git-commit: fcedba42d94ecdc14ca13d3797cba1ccbf743fa4
Patch-mainline: v4.19-rc1
References: bsc#1104967,FATE#325924

This patch removes the duplicate initialization of q->queue_head
in the blk_alloc_queue_node(). This removes the 2nd initialization
so that we preserve the initialization order same as declaration
present in struct request_queue.
