[janitor] sis900: don't use yield()

["Randy.Dunlap" <rddunlap@xxxxxxxx>]

From: maximilian attems <janitor@xxxxxxxxxxxxxx>

thanks to Felipe W Damasio hint rediffed.
patch is on top of linux-2.6.6-rc2

yield() removes process from active array into expired array,
better just yield the CPU for a bit.
tested on my laptop with a sis900.
