Bug description
Linked external sftp storage, where some folders are not readable to the user, as it is common in shared storages, are only partially visible. Scanning the storage stops on the first encounter of an inaccessible folder.
Entering folder with no permission through the website throws an error "Storage is temporarily not available". The website remains in a somewhat broken state, as the current folder is not read.
Steps to reproduce
- Link an enternal storage via sftp
- Make some folder not readable
- Try to enter that folder.
Expected behavior
Not readable folders should render emtpy, at least that was the former behaviour.

Additional info
This bug was introduces as a side effect of #43787 . Prior to the PR unreadable folders failed silently and rendered empty, while now scanning the storage stops with "Storage is temporarily not available". As the behaviour was introduced into Storage/common.php it probably effects other external storage systems as well.
