[PATCH] x86_64 irq: Simplfiy the set_affinity logic.

For some reason the code has been picking TARGET_CPUS when asked to
set the affinity to an empty set of cpus.  That is just silly it's
extra work.  Instead if there are no cpus to set the affinity to we
should just give up immediately.  That is simpler and a little more
intuitive.
