Subject: [PATCH] block: move blk_stat_add() to __blk_mq_end_request()
Git-commit: 4bc6339a583cec650b05d6fdcc83f03f941c1a3b
Patch-mainline: v4.18-rc1
References: bsc#1104967,FATE#325924

We want this next to blk_account_io_done() for the next change so that
we can call ktime_get() only once for both.
