cpu/x86/lapic: Fix SMP=n case with LEGACY_SMP_INIT
Fix regression after commit 9ec7227c9b
cpu/x86/lapic: Move LAPIC configuration to MP init
The call to disable_lapic() got removed and with asus/p2b
SeaBIOS payload was unable to load kernel.
The combination of entering SeaBIOS payload with an
enabled lapic but not having programmed LAPIC_LVT0
for DELIVERY_MODE_EXTINT apparently disconnects i8259
PIC interrupt delivery pin.
