kyber: make trace_block_rq call consistent with documentation
[ Upstream commit fb7b9b0231ba8f77587c23f5257a4fdb6df1219e ]
The kyber ioscheduler calls trace_block_rq_insert() *after* the request
is added to the queue but the documentation for trace_block_rq_insert()
says that the call should be made *before* the request is added to the
queue. Move the tracepoint for the kyber ioscheduler so that it is
consistent with the documentation.
