Have nfs ->d_revalidate() report errors properly
If nfs atomic open implementation ends up doing open request from ->d_revalidate() codepath and gets an error from server, return that error to caller explicitly and don't bother with lookup_instantiate_filp() at all. ->d_revalidate() can return an error itself just fine... See http://bugzilla.kernel.org/show_bug.cgi?id=15674 http://marc.info/?l=linux-kernel&m=126988782722711&w=2 for original report.
