Revert "sbitmap: fix batched wait_cnt accounting"

Browse Source 
This reverts commit 16ede66973.

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.
