From: Phil Sutter <phil@xxxxxx>
Without this, a stale pointer remains in pernet loggers after module
unload causing a kernel oops during dereference. Easily reproduced by:
| # modprobe nf_log_syslog
| # rmmod nf_log_syslog
| # cat /proc/net/netfilter/nf_log
Fixes: 77ccee96a6742 ("netfilter: nf_log_bridge: merge with nf_log_syslog")
