blk-throttle: remove spurious throtl_enqueue_tg() call from throtl_select_dispatch()
throtl_select_dispatch() calls throtl_enqueue_tg() right after tg_update_disptime(), which always calls the function anyway. The call is, while harmless, unnecessary. Remove it. This patch doesn't introduce any behavior difference. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Vivek Goyal <vgoyal@redhat.com>
