[PATCH] fix pdeath_signal SMP locking

Obviously almost noone uses the pdeath_signal feature, since this has gone
unnoticed for quite some time.

This patch calls the function that does the right locking for the context
of this call (inside exit_notify).  The names of the signal.c entrypoints
are a little confusing.
