x86/apic: Fix build failure with X86_IO_APIC disabled

My backport of commit 2e63ad4bd5dd "x86/apic: Do not init irq
remapping if ioapic is disabled" added an unconditional use of
skip_ioapic_setup.  Enabling X86_LOCAL_APIC but not X86_IO_APIC
results in a build failure.

This configuration was made impossible by commit b1da1e715d4f
"x86/Kconfig: Simplify X86_IO_APIC dependencies", but that seems to
depend on additional changes that aren't suitable for stable.

The function that was changed, enable_IR_x2apic(), is only used in
64-bit configurations where CONFIG_X86_IO_APIC is always enabled.  So
extend the #ifdef CONFIG_X86_64 section to include this function.
