NFS: Serialise O_DIRECT i/o and truncate()

[ Upstream commit 9eb90f435415c7da4800974ed943e39b5578ee7f ]

Ensure that all O_DIRECT reads and writes are complete, and prevent the
initiation of new i/o until the setattr operation that will truncate the
file is complete.

Fixes: a5864c999de6 ("NFS: Do not serialise O_DIRECT reads and writes")
