syzkaller at:

https://syzkaller.appspot.com/bug?id=08f12df95ae7da69814e64eb5515d5a85ed06b76

The first patch in the series fixes the issue and the second patch does
some refactoring to avoid duplicate code.

Changes in v3:
- Split the patch into two patches
- Remove the convenience wrappers as suggested by Shuah
- Remove the WARN as suggested by Greg

Changes in v2:
Use WARN_ON() instead of BUG() when unlink_list is neither unlink_tx nor
unlink_rx.
