Jeff Layton 645c1b4b13 nfsd: make a copy of struct iattr before calling notify_change
[ Upstream commit d53d70084d27f56bcdf5074328f2c9ec861be596 ]

notify_change can modify the iattr structure. In particular it can
end up setting ATTR_MODE when ATTR_KILL_SUID is already set, causing
a BUG() if the same iattr is passed to notify_change more than once.

Make a copy of the struct iattr before calling notify_change.
