irq_work: Fix build failure when CONFIG_IRQ_WORK is not defined
When CONFIG_IRQ_WORK is not defined (difficult to do, as it also
requires CONFIG_PRINTK not to be defined), we get a build failure:
kernel/built-in.o: In function `flush_smp_call_function_queue':
kernel/smp.c:263: undefined reference to `irq_work_run'
kernel/smp.c:263: undefined reference to `irq_work_run'
Makefile:933: recipe for target 'vmlinux' failed
Simplest thing to do is to make irq_work_run() a nop when not set.
