URL: https://github.com/apache/trafficserver/pull/11906

   Prior to the change, when `StripeSM::handle_dir_clear` faced an error, it 
set `fd = -1`. However, when  `CacheProcessor::mark_storage_offline` makes a 
bad `CacheDisk` offline, it's comparing `CacheDisk::fd` and `StripeSM::fd`.

   This might mess below metrics
   
   - `proxy.process.cache.direntries.total`
   - `proxy.process.cache.direntries.used`
   - `proxy.process.cache.bytes_total`
   
   FWIW, rebuilding Stripe Hash Table seems not affected by this.
