Subject: [PATCH] Fix crash with SCHED_IDLE policy
References: bnc#959992

There are two new schduling policies to be recognized by cset.  SCHED_ISO and
SCHED_IDLE.  The former is not yet implemented in Linux kernel so we write out
'???' when we encounter its code.  For the latter there is the string 'idl'.
