The fix does indeed suppress the error messages.  But it does not
change that Emacs forgets that the new file is a remote file.

Find file /sshfs:otherhost:/tmp/newfile
(buffer-file-name) => "/tmp/tramp.sshfs.otherhost/tmp/newfile"
(file-remote-p (buffer-file-name)) => nil

Find file /sshfs:otherhost:/tmp/oldfile
(buffer-file-name) => "/sshfs:otherhost:/tmp/oldfile"
(file-remote-p (buffer-file-name)) => "/sshfs:otherhost:"
