cw1200: Use a threaded oneshot irq handler for cw1200_spi
This supercedes the older patch ("cw1200: Don't perform SPI transfers in interrupt context") that badly attempted to fix this problem. This is a far simpler solution, which has the added benefit of actually working. Signed-off-by: Solomon Peachy <pizza@shaftnet.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
