We have an array of UDP connections so just go through
the list in a most simple way. Set only the UDP connection
pointer if we found something and clear it otherwise.
This helps to avoid weird errors where multiple UDP connections
were added but only the first one was found during list traversal.

The net_reply() can be used if the application wants to reply
something to peer right after receiving the data. The function
will reverse the source and destination addresses and ports,
and set the uIP internal structures in such a way that the
reply is possible. Using this function saves the application
from allocating a separate net_buf for just sending simple
message back.
