bfq-iosched: remove unused variable
bfqd->sb_shift was attempted used as a cache for the sbitmap queue shift, but we don't need it, as it never changes. Kill it with fire. Acked-by: Paolo Valente <paolo.valente@linaro.org> Reviewed-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
