[XFS] make inode reclaim wait for log I/O to complete
During a forced shutdown a xfs inode can be destroyed before log I/O involving that inode is complete. We need to wait for the inode to be unpinned before tearing it down. Version 2 cleans up the code a bit by relying on xfs_iflush() to do the unpinning and forced shutdown check.
