Subject: [PATCH net-next v2 5/5] netconsole: pass wctxt to send_msg_udp()
 for consistency

Refactor send_msg_udp() to take a struct nbcon_write_context pointer
instead of separate msg and len parameters. This makes its signature
consistent with send_ext_msg_udp() and prepares the function for
future use of execution context information from wctxt.

No functional change.
