The netfs_io_stream::front member is meant to point to the subrequest
currently being collected on a stream, but it isn't actually used this way
by direct write (which mostly ignores it). However, there's a tracepoint
which looks at it. Further, stream->front is actually redundant with
stream->subrequests.next.
Fix the potential problem in the direct code by just removing the member
and using stream->subrequests.next instead, thereby also simplifying the
code.
