This fixes a very special case that can be reproduced by just disconnecting a disk at runtime, and without unmounting the filesystem first, start scrub on the filesystem with the disconnected disk. All read and write EIOs are handled correctly, only the first superblock is an exception and gives a BUG() in a subfunction. The BUG() is correct, it would crash later otherwise. The subfunction must not be called for superblocks and this is what the fix changes. Reported-by:
