orangefs: do not check possibly stale size on truncate
Let the server figure this out because our size might be out of date or
not present.
The bug was that
xfs_io -f -t -c "pread -v 0 100" /mnt/foo
echo "Test" > /mnt/foo
xfs_io -f -t -c "pread -v 0 100" /mnt/foo
fails because the second truncate did not happen if nothing had
requested the size after the write in echo. Thus i_size was zero (not
present) and the orangefs_setattr though i_size was zero and there was
nothing to do.
