[XFS] xfssyncd is responsible for flushing inode or device's data by
extracting the work from its queue. In addition, this processing also decrement the inode's i_count. If there are any remaining works in queue before this process terminates, we have unbalanced increment and decrement of i_count. Thus it can cause assertion failure of vn_count. The fix allows xyssyncd to process any remaining work before it is shutdown.
