Gary Lin 0e8c17fd80 bpfilter: Specify the log level for the kmsg message
[ Upstream commit a196fa78a2 ]

Per the kmsg document [0], if we don't specify the log level with a
prefix "<N>" in the message string, the default log level will be
applied to the message. Since the default level could be warning(4),
this would make the log utility such as journalctl treat the message,
"Started bpfilter", as a warning. To avoid confusion, this commit
adds the prefix "<5>" to make the message always a notice.
