rG42f2fa9953da: sockets: don't call dom_dispose() on a listening socket
Summary

sorflush() already did the right thing, so only sofree() needed
a fix. Turn check into assertion in our only dom_dispose method.

Does this fix a bug? It's not obvious to me if so. Setting UNPGC_IGNORE_RIGHTS on the listening socket should be harmless.

There is no bug here. The disposal is a socket buffer operation, so better do the check one layer up. This is a preparation before merging: sorflush(), dom_dispose, pru_flush and pru_shutdown into a single pru_shutdown method.
