Impact: cleanup
1. add smp_intr_init and apic_intr_init for 32bit, the same as 64bit
2. move the apic_intr_init() call before set gate with interrupt[i]
3. for 64bit, if ia32_emulation is not used, will make per_cpu to use 0x80 vector.
[ v2: should use !test_bit() instead of test_bit() with 32bit ]
