LU-12026 mdt: MDS stores atime|mtime|ctime during close
In order to make direct inode scanning on the MDT useful, in
addition to storing the file size/blocks via LSOM on the MDT, we
also need to store the atime/mtime/ctime on the MDT inodes.
Currently the atime is already lazily updated on the MDS (at
close time). In this patch, the final mtime/ctime are sent to the
MDS at close time and updated on the MDT inode, and make MDT-only
scanning workable.
