The very first thing free_res does is the same lock/signal/unlock
sequence, so there is no reason to open code it before calling
free_res.

res->sync_res always exists at this point so remove the assert too.

v3:
- Delete stray edit

Bart, Yes, must have been a stray editor edit, I did not even look at v2 in
the mailer before sending it, since the one line change was so simple :(
This one compiles.
