Revert "sbitmap: fix batched wait_cnt accounting"
This reverts commit 16ede66973c84f890c03584f79158dd5b2d725f5.
This is causing issues with CPU stalls on my test box, revert it for
now until we understand what is going on. It looks like infinite
looping off sbitmap_queue_wake_up(), but hard to tell with a lot of
CPUs hitting this issue and the console scrolling infinitely.
