[PATCH 2/4] firewire: ohci: replace request_irq() with request_threaded_irq()

[Takashi S. <o-t...@sa...>]

Nowadays request_irq() is a wrapper of request_threaded_irq(). The IRQ
handler of 1394 ohci driver has never been optimized yet, while it is
a good preparation for the future work to replace the latter.

This commit replaces the former.
