Good catch....

But the wrong fix. The code *used* to have returns like this all over the
place, but that meant it returns with a lock held - whoops.  The *other* 287 or
so places I changed to 'ret = FFS_yaddayadda',  followed by a 'goto out' but I
apparently missed one.

And thanks a bunch for feeding it to Coverity :)
