Hitoshi Mitake 498f21405a sheepdog: use per AIOCB dirty indexes for non overlapping requests 
In the commit 96b14ff85acf, requests for overlapping areas are
serialized. However, it cannot handle a case of non overlapping
requests. In such a case, min_dirty_data_idx and max_dirty_data_idx
can be overwritten by the requests and invalid inode update can
happen e.g. a case like create(1, 2) and create(3, 4) are issued in
parallel.

This patch lets SheepdogAIOCB have dirty data indexes instead of
BDRVSheepdogState for avoiding the above situation.

This patch also does trivial renaming for better description:
overwrapping -> overlapping
