Revert a thinko in commit d2f119fe319528da8c76a1107459d6f478cbf28c:
When knodemgrd starts, it needs to sleep until host->generation was
incremented above its initial value of 0. My wrong logic caused it to
start sending requests when the bus wasn't completely ready. Seen as
"AT dma reset ctx=0, aborting transmission" messages in 2.6.19-rc1.
