My earlier commit 10e6e65 deserves a layer or two of brown paper
bags. The logic in that commit means that a CRC failure on the
primary superblock will *never* result in an error return.
Hopefully this fixes it, so that we always return the error
if it's a primary superblock, otherwise only if the filesystem
has CRCs enabled.
