[PATCH 2/2] x86/apic: Convert APIC_INTEGRATED to lapic_is_integrated() in apic.c

[Dou Liyang]

Currently, lapic_is_integrated() encapsulates APIC_INTEGRATED() in
apic.c for a concise call.

But lapic_get_maxlvt() is overlooked.

Convert to lapic_is_integrated() and fix two code formats.

No functionality change
