[dm-devel] Revert "dm space maps: don't reset space map allocation cursor when committing"

[luomeng]

Because thin-pool is storage over-commitment, one of the following 
scenarios exists: constantly create and delete file, then the search 
doesn't hit the end of the metadata device, but ramdisk hits the end 
(not support discard). So the cursor doesn't reset.
