kernel - Fix deep stack recursion in unix domain socket garbage collection
* A chain of unix domain sockets with the previous fd passed into the
next one can cause a kernel stack overflow.
* Flatten the portion of the gc which would otherwise recurse by placing
the fp on a list instead of calling a nested closef(), then running
the closes at the top level.
