tracing: Fix null pointer deref with SEND_SIG_FORCED
BUG: unable to handle kernel NULL pointer dereference at
0000000000000006
IP: [<ffffffff8107bd37>] ftrace_raw_event_signal_generate+0x87/0x140
TP_STORE_SIGINFO() forgets about SEND_SIG_FORCED, fix.
We should probably export is_si_special() and change TP_STORE_SIGINFO()
to use it in the longer term.
