Subject: [REVIEW][PATCH 10/20] signal/x86/traps: Use force_sig instead of open coding it.

The function "force_sig(sig, tsk)" is equivalent to "
force_sig_info(sig, SEND_SIG_PRIV, tsk)".  Using the siginfo variants can
be error prone so use the simpler old fashioned force_sig variant,
and with luck the force_sig_info variant can go away.
