[LU-9284] striped directory should be able to be accessed even if one stripe MDT is failed.

Description

In current striped directory implementation, if one stripe MDT failed, the striped directory will not be able to access, which seems unacceptable. So in this case

1. lfs getdirstripe should indicate which stripe is failed.
2. the left stripes should be able to be accessed, and can be migrated to a new directory.
3. creating the file/dir on the failed stripe should fail, though it should succeed on other stripes.

Other suggestions? If some else already create the ticket, please close this one. Thanks.

This looks to be duplicate of LU-9206, Di, is it? But your description is more thorough and useful, thanks.
