    nfs: newnfs_setroot(): Remove an obsolete comment
    
    This comment is obsolete, as:
    1. This code is FreeBSD-specific and is not shared with other BSDs.
    2. With our recent changes in commit be1f7435ef218b1d ("kern: start
       tracking cr_gid outside of cr_groups[]"), all of NetBSD, OpenBSD and
       FreeBSD have the effective GID in a separate field (DragonFlyBSD
       remains to this day an outlier).
    
    MFC after:      9 days
    Sponsored by:   The FreeBSD Foundation
    Differential Revision:  https://reviews.freebsd.org/D52254
    
    (cherry picked from commit 67f8bd5986a42a173ef9082abfcd523b1a3ac056)
