Aborting on SCLP READ SCP INFO error leads to a deadloop.
The loop is:
abort() -> exit() -> smp_teardown() -> smp_query_num_cpus() ->
sclp_get_cpu_num() -> assert() -> abort()
Since smp_setup() is done after sclp_read_info() inside setup() this
loop only happens when only the start processor is running.
Let sclp_get_cpu_num() return 1 in this case.
