Revert "udp_recv: Close receiver after 5 seconds of inactivitly."

This reverts commit 4d4379901a0a01859728d56795a7ab6ada9c876b.

This was not really a good idea as it only papers over the real bug.
A better fix is to check whether the currently active buffer tree
matches the status information obtained from para_server. This will
be implemented in a subsequent patch.
