[PATCH] [RFC] i386/i386_mainbus: fix the build when MPBIOS and ACPI are disabled

[Paolo Pisati <p.pisati%gmail.com@localhost>]

In sys/arch/i386/i386/i386_mainbus.c::i386_mainbus_rescan() mp_pci_scan() is
only executed if:

...
                if (npcibus == 0 && mpacpi_active)
                        npcibus = mp_pci_scan(self, &mba.mba_pba, pcibusprint);
                if (npcibus == 0 && mpbios_scanned != 0)
                        npcibus = mp_pci_scan(self, &mba.mba_pba, pcibusprint);
...

hence follow the same condition during the unwind.
