Description

I have a ozone cluster, prefix is enable when setup cluster. when restart om, then error below:

java.io.IOException: Failed to start OM in PREFIX layout format as existing bucket has a different layout SIMPLE metadata format

This issue is similar to HDDS-5094. Later in HDDS-5362, bucket layout is supported, then addFSOptimizedBucketDetails is removed in this https://github.com/apache/ozone/commit/7df192530810a07d3b976c3a56c46328c0b1d591. So om crash when restart if layout is PREFIX.

I think there is no need to validate bucket type since HDDS-5362.
