Sven Schnelle c185f13918 s390/smp: perform initial CPU reset also for SMT siblings
commit b5e438ebd7 upstream.

Not resetting the SMT siblings might leave them in unpredictable
state. One of the observed problems was that the CPU timer wasn't
reset and therefore large system time values where accounted during
CPU bringup.
