Move the static buffers from send_msg_no_fragmentation() and send_msg_fragmented() into the netconsole_target structure. This simplifies the code by:
- Eliminating redundant static buffers
- Centralizing buffer management in the target structure
- Reducing memory usage by 1KB (one buffer instead of two)
The buffer in netconsole_target is protected by target_list_lock, maintaining the same synchronization semantics as the original code.

nit: buf should also be added to the Kernel doc for this structure.
