Sridhar, thanks, this indeed fixed the problems that Roger was
having, I tested this in vmware using unix sockets as modules and running
a full gnome2 installation + gkrellm.

o net/socket: fix bug in sys_accept
module_put() gets called twice on error. Once via the explicit module_put and
the second via sock_release(). Also i think we should do a __module_get() with
newsock's owner(although same as the original listening sock).
