Fix leak that may occur when xmlnode_from_str fails

Fix leak that may occur when xmlnode_from_str fails
The failure may occur any time in the middle of parsing, and `xpd->current` may
not actually be pointing to the root of the parsed tree. Thus we need to walk
back up before freeing the xmlnode.
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=34988
Testing Done:
Ran the reproducer testcase on `fuzz_xml`
