fs/9p: Don't use O_TRUNC flag in TOPEN and TLOPEN request
We do the truncate via setattr request, hence don't pass the O_TRUNC flag in open request. Without this patch we end up sending zero sized write request to server when we try to truncate. Some servers (VirtFS) were not handling that properly. Reported-by: M.
