Ryusuke Konishi 97d3e94031 nilfs2: do not acquire rwsem in nilfs_bmap_write() 
It is now clear that nilfs_bmap_write() is only used to finalize logs
written to disk.  Concurrent bmap modification operations are not
performed on bmaps in this context.  Additionally, this function does not
modify data used in read-only operations such as bmap lookups.

Therefore, there is no need to acquire bmap->b_sem in nilfs_bmap_write(),
so delete it.
