dmar, x86: Use function stubs when CONFIG_INTR_REMAP is disabled 



The stubs for CONFIG_INTR_REMAP disabled need to be functions
instead of values to eliminate build warnings.

 arch/x86/kernel/apic/apic.c: In function 'lapic_suspend':
 arch/x86/kernel/apic/apic.c:2060:3: warning: statement with no effect
 arch/x86/kernel/apic/apic.c: In function 'lapic_resume':
 arch/x86/kernel/apic/apic.c:2137:3: warning: statement with no effect
