[nfs-utils PATCH 5/8] nfsiostat: make comment explain mount/unmount more broadly

[Frank Sorenson <sorenson@redhat.com>]

The comment explaining the need to recheck the devices list
suggests that nfs mounts/unmounts may occur when automount
is involved, but they can happen for other reasons as well.

Make the comment explain the issue more broadly.
