signals: do_group_exit(): use signal_group_exit() more consistently do_group_exit() checks SIGNAL_GROUP_EXIT to avoid taking sighand->siglock. Since ed5d2cac114202fe2978a9cbcab8f5032796d538 exec() doesn't set this flag, we should use signal_group_exit(). This is not needed for correctness, but can speedup the multithreaded exec and makes the code more consistent.
