net: context: Fix connect for UDP contexts
net: context: Fix connect for UDP contexts

Similar to the socket connect() call, calling connect for a UDP
context needs to set both local and remote addresses and port
number. Fix this not to be exclusive for TCP.

Similarly, the remote destination can be a multicast address when
UDP is used.
