task_work: make TWA_NMI_CURRENT handling conditional on IRQ_WORK
The TWA_NMI_CURRENT handling very much depends on IRQ_WORK, but that
isn't universally enabled everywhere.
Maybe the IRQ_WORK infrastructure should just be unconditional - x86
ends up indirectly enabling it through unconditionally enabling
PERF_EVENTS, for example. But it also gets enabled by having SMP
support, or even if you just have PRINTK enabled.
But in the meantime TWA_NMI_CURRENT causes tons of build failures on
various odd minimal configs. Which did show up in linux-next, but
despite that nobody bothered to fix it or even inform me until -rc1 was
out.
Fixes: 466e4d801cd4 ("task_work: Add TWA_NMI_CURRENT as an additional notify mode")
