r8021: we only need to return STATUS_BUFFER_OVERFLOW for the ipc_trans replies
and not for the ipc_read() replies as here the client explicit says how much data it wants the write_fn() in dcesrv_output() now returns NTSTATUS and the ipc specific implementations are moved to the ntvfs_ipc module metze (This used to be commit fe483dcd874b7243d61e9623840c672b4ea06b2c)
