[PATCH] sigio: cleanup, don't take tasklist twice
The only user of send_sigio_to_task() already holds tasklist_lock, so it is
better not to send the signal via send_group_sig_info() (which takes
tasklist recursively) but use group_send_sig_info().
The same change in send_sigurg()->send_sigurg_to_task().
