LU-14470 dne: striped mkdir replay by client request

Once all involved MDTs of a striped mkdir were rebooted, or MDT
recovery was aborted, this mkdir will be replayed by client request.
To correctly replay such mkdir, pack directory LMV in mkdir reply,
and save it to request from reply, and MDS should use this layout to
replay mkdir.

For MDT recovery abort case, the original mkdir may be partially
executed, so mkdir replay should check below cases and don't treat
them as error:
* name entry is found on parent directory on remote MDT.
* stripe exists on remote MDT.

For backward compatibility, Add MDS_MKDIR_LMV flag to indicate a
client requires directory LMV in mkdir reply.

Updated replay-single 100c since striped mkdir can replay now.

Updated recovery-small 130 since create fetches layout now.

Added replay-single 100e.
