In the SETATTR code, if the changes to a & m time are exclusively 

set via NFSV3SATTRTIME_TOSERVER and not NFSV3SATTRTIME_TOCLIENT,
add VA_UTIMES_NULL to the va_vflags. This reflects our policy
where we're much more liberal about who can set a & m times to 'now'
than we are about who can set them to a specific time.

Should close PR 15597 from Martin Husemann. Patch is based on the
one Matthias Drochner gave in the PR.
