Btrfs-progs: fsck: deal with corrupted csum root

If checksum root is corrupted, fsck will get segmentation. This
is because if we fail to load checksum root, root's node is NULL which
cause NULL pointer deferences later.

To fix this problem, we just did something like extent tree rebuilding.
Allocate a new one and clear uptodate flag. We will do sanity check
before fsck going on.
