x86/microcode: Run the AP-loading routine only on the application processors
cpu_init() is run also on the BSP (in addition to the APs): x86_64_start_kernel |-> x86_64_start_reservations |-> start_kernel |-> trap_init |-> cpu_init |-> load_ucode_ap ... but we run the AP (Application Processors) microcode loading routine there too even though we have a BSP-specific routine for that: load_ucode_bsp(). Which is unnecessary. So let's limit the AP microcode loading routine to the APs only. Remove a useless comment while at it.
