cfq-iosched: Get rid of unnecessary local variable
Use of local varibale "n" seems to be unnecessary. Remove it. This brings it inline with function __cfq_group_st_add(), which is also doing the similar operation of adding a group to a rb tree. No functionality change here. Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Acked-by: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Tejun Heo <tj@kernel.org>
