Btrfs: fix kfree on list_head in btrfs_lookup_csums_range error cleanup

commit 6e5aafb2 upstream.

If we hit any errors in btrfs_lookup_csums_range, we'll loop through all
the csums we allocate and free them.  But the code was using list_entry
incorrectly, and ended up trying to free the on-stack list_head instead.

This bug came from commit 0678b618
