x86: CFI hardening for request_irq()

... and friends; alloc_direct_apic_vector() and set_direct_apic_vector().

Control Flow Integrity schemes use toolchain and optionally hardware support
to help protect against call/jump/return oriented programming attacks.

Use cf_check to annotate function pointer targets for the toolchain.
