s390/smp: fix cpu re-scan vs. cpu state
The cpu-info array starts with a list of cpus in configured state, followed by the cpus in standby state. The comparison to decide which state a cpu has is incorrect, this causes configured cpus appear as standby cpus. The correct comparison is the index of the new cpu in the cpu-info array vs. the number of configured cpus. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
