nvme: don't warn on block content change effects

mainline inclusion
from mainline-5.1
commit 415df90b
category: bugfix
bugzilla: NA
CVE: NA

-------------------------------------------------

A write or flush IO passthrough command is expected to change the
logical block content, so don't warn on these as no additional handling
is necessary.
