e2fsck: reopen the file system with saved flags after a journal replay
After a journal replay, we close and reopen the file system so that
any changes in the superblock can get reflected in the libext2fs's
internal data structures. We need to save the flags passed to
ext2fs_open() that we used when we originally opened the file system.
Otherwise we will end up not be able to repair a file system which
requires a journal replay and which has bigalloc enabled or which has
more than 2**32 blocks; e2fsck will abort with the error message:
fsck.ext4: Filesystem too large to use legacy bitmaps while trying to re-open
