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 <[email protected]> Acked-by: Jeff Moyer <[email protected]> Signed-off-by: Tejun Heo <[email protected]>
