x86, intr-remap: fix x2apic/intr-remap resume

Browse source

Interrupt remapping was decoupled from x2apic. Shouldn't check
x2apic before resume interrupt remapping. Otherwise, interrupt
remapping won't be resumed when x2apic is not enabled.

[ Impact: fix potential intr-remap resume hang on !x2apic ]
