Made nsmux wait until dynamic translators finish

Previously, a settrans -gR on a node on which nsmux resides
would only kill the dynamic translators, without shutting
down nsmux, because it didn't wait for the children to close
their ports, which made a check in netfs_shutdown fail. Now
nsmux waits for the dynamic translator to finish, so
settrans -gR does its job as expected: shuts down everything.
