genirq: fix comment to say IRQ_WAKE_THREAD

Trying to implement a driver to use threaded irqs, I was confused when the
return value to use that was described in the comment above
request_threaded_irq was not defined.

Turns out that the enum is IRQ_WAKE_THREAD where as the comment said
IRQ_THREAD_WAKE.

[Impact: do not confuse developers with wrong comments ]
