Subject: [PATCH] block: fix the count of PGPGOUT for WRITE_SAME
References: bsc#1077989
Git-commit: 7c5a0dcf557c6511a61e092ba887de28882fe857
Patch-mainline: v4.16-rc4
The vm counters is counted in sectors, so we should do the conversation
in submit_bio.
Fixes: 74d46992e0d9 ("block: replace bi_bdev with a gendisk pointer and partitions index")
