If CONFIG_PPC_SPLPAR is not selected, steal_time will always be NUL, so accounting it is pointless
Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> --- v5: moved the change to the original localtion v4: removed the check in vtime_account_system(), the compiler removes the code regardless. v3: new
