Oleg Nesterov ffdf91856c ia64: ptrace_attach_sync_user_rbs: avoid "task->signal != NULL" checks
Preparation to make task->signal immutable, no functional changes.

It doesn't matter which pointer we check under tasklist to ensure the task
was not released, ->signal or ->sighand.  But we are going to make
->signal refcountable, change the code to use ->sighand.

Note: this code doesn't need this check and tasklist_lock at all, it
should be converted to use lock_task_sighand().  And, the code under
SIGNAL_STOP_STOPPED check looks wrong.
