pid_ns: zap_pid_ns_processes: use SEND_SIG_NOINFO instead of force_sig()
zap_pid_ns_processes() uses force_sig(SIGKILL) to ensure SIGKILL will be
delivered to sub-namespace inits as well. This is correct, but we are
going to change force_sig_info() semantics. See
http://bugzilla.kernel.org/show_bug.cgi?id=15395#c31
We can use send_sig_info(SEND_SIG_NOINFO) instead, since
614c517d7c00af1b26ded20646b329397d6f51a1 ("signals: SEND_SIG_NOINFO should
be considered as SI_FROMUSER()") SEND_SIG_NOINFO means "from user" and
therefore send_signal() will get the correct from_ancestor_ns = T flag.
