[Bugfix 1/5] x86/irq: Do not reuse struct apic_chip_data.old_domain as temporary buffer

Function __assign_irq_vector() makes use of apic_chip_data.old_domain as a temporary buffer, which causes trouble to rollback logic in case of failure. So use a dedicated temporary buffer for __assign_irq_vector(). Signed-off-by: Jiang Liu --- arch/x86/kernel/apic/vector.c |9 + 1
