Oleg Nesterov dd98acf747 keyctl_session_to_parent(): use thread_group_empty() to check singlethreadness 
No functional changes.

keyctl_session_to_parent() is the only user of signal->count which needs
the correct value.  Change it to use thread_group_empty() instead, this
must be strictly equivalent under tasklist, and imho looks better.
