#1503100 — [PATCH] nfs4: fix missing-braces warning

A bugfix introduced a harmless warning for update_open_stateid:

fs/nfs/nfs4proc.c:1548:2: error: missing braces around initializer [-Werror=missing-braces]

Removing the zero in the initializer will do the right thing here
and initialize the entire structure to zero.

Fixes: 1393d9612ba0 ("NFSv4: Fix a race when updating an open_stateid")

#1504257

Hi Arnd (and Geert, if you're out there. I keep getting "relay access denied" when I try to CC you),

Thanks for the patches for this issue!  I've applied Arnd's version for 4.9-rc* since I think it looks a little cleaner.

Cheers,
Anna
