nfsd: update create verifier comment
[ Upstream commit 2336d69686
]
I don't know if that Solaris behavior matters any more or if it's still
possible to look up that bug ID any more. The XFS behavior's definitely
still relevant, though; any but the most recent XFS filesystems will
lose the top bits.
