libext2fs: retry reading superblock on open when checksum is bad

When opening a file system which is mounted, it's possible that when
ext2fs_open2() is racing with the kernel modifying the orphaned inode
list, the superblock's checksum could be incorrect.  So retry reading
the superblock in the hopes that the problem will self-correct.
