Subject: [PATCH] block: change return type to bool
Git-commit: 599d067dd3c1b9697b786c992b17cd6529c0459c
Patch-mainline: v4.19-rc1
References: bsc#1104967,FATE#325924

Because blk_do_io_stat() only does a judgement about the request
contributes to IO statistics, it better changes return type to bool.
