x86: keep MP_intsrc_info untouched if we do not update mptable
Daniel Exner reported IO-APIC enumeration breakage in linux-next. Alexey Starikovskiy found out that it might be related to commit 2944e16b25 "x86: update mptable". use enable_update_mptable to decide if need check before add mp_irqs array.
