[XFS] Fix inode size update before data write in xfs_setattr
When changing the file size by a truncate() call, we log the change in the
inode size. However, we do not flush any outstanding data that might not
have been written to disk, thereby violating the data/inode size update
order. This can leave files full of NULLs on crash.
Hence if we are truncating the file, flush any unwritten data that may lie
between the curret on disk inode size and the new inode size that is being
logged to ensure that ordering is preserved.
