Subject: [PATCH] NVMe: Fix incompatible pointer type warnings

Commit 6a4d55146334 ("block: prep work for batch completion")
added a struct batch_complete * as a third argument to bi_end_io.
This patch adds the missing third argument to the nvme_bio_pair_endio
function.

Sparse output:

drivers/block/nvme-core.c: In function ‘nvme_bio_split’:
drivers/block/nvme-core.c:483:19: warning:
assignment from incompatible pointer type [enabled by default]
drivers/block/nvme-core.c:484:19: warning:

That patch isn't in Linus' tree yet, so we can't apply this patch. It needs
to go to linux-next.
