[IA64] Do not call SN_SAL_SET_CPU_NUMBER twice on cpu 0
This is an SN specific patch.
Architectually, cpu_init is always called twice on cpu 0
and thus resulted in two SN_SAL_SET_CPU_NUMBER calls.
This was harmless in production kernel; however, it can
cause problem on booting up a crashdump kernel at Altix.
Here is the patch that detects the second sn_cpu_init
call and skips the second call to SN_SAL_SET_CPU_NUMBER.
