Since commit 04d2c8c83d ("printk: convert the format for KERN_<LEVEL> to
a 2 byte pattern"), printk no longer uses a "<.>" string prefix
internally, so the call in xt_LOG ends up emitting the prefix as part of
the log itself (and possibly not at the configured level).
To avoid having to worry about printk's internal formatting, switch to
printk_emit(), specifying the desired level directly.
