[PATCH net-next v3 6/8] netconsole: improve code style in parser function

[Breno Leitao]

Split assignment from conditional checks and use preferred null pointer
check style (!delim instead of == NULL) in netconsole_parser_cmdline().
This improves code readability and follows kernel coding style
conventions.
