Subject: Kabi fixup blk_mq_register_dev()
References: bsc#1140637
Patch-mainline: Never, KABI consistency

This is a kabi consistency patch for
patches.fixes/blk-mq-free-hw-queue-s-resource-in-hctx-s-release-handler.patch.

patches.fixes/blk-mq-free-hw-queue-s-resource-in-hctx-s-release-handler.patch
adds "block/blk.h" to block/blk-mq-sysfs.c in order to get the definitions for
blk_free_flush_queue().

But adding "block/blk.h" breaks the kABI for blk_mq_register_dev() by making
it more defined.

Fix this by removing the include and pulling the definition in as an "extern"
