x86/apic: Simplify enable_IR_x2apic(), remove try_to_enable_IR()
The following commit:
2e63ad4bd5dd ("x86/apic: Do not init irq remapping if ioapic is disabled")
... added a check for skipped IO-APIC setup to enable_IR_x2apic(), but this
check is also duplicated in try_to_enable_IR() - and it will never succeed in
calling irq_remapping_enable().
Remove the whole irq_remapping_enable() complication: if the IO-APIC is
disabled we cannot enable IRQ remapping.
