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.
