nfsd4: remove unused dl_trunc
There's no point in keeping this field around--it's always zero. (Background: the protocol allows you to tell the client that the file is about to be truncated, as an optimization to save the client from writing back dirty pages that will just be discarded. We don't implement this hint. If we do some day, adding this field back in will be the least of the work involved.) Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
