Marco Patalano found missing NVMe optimized/inaccessible paths when
executing "nvme list-subsys" command with native multipathing disabled.
He was able to git bisect this back to 6d0f426e ("nvme: fix multipath
crash when ANA is deactivated"). The problem is the check for multipath,
removing this is similar to RHEL commit 158eef2e ("nvme: allow ANA support
to be independent of native multipathing"), I did leave the existing
comment in place for future back ports and as a reminder to watch for
these changes in the future.

Bugzilla: 1790958
Build info: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=26061480
Upstream: RHEL only
Test: QE verified "nvme list-subsys" command and did sanity check with native
multipathing disabled.
