[PATCH nf-next] netfilter: nfnetlink_log: add "nf-logger-3-1" module alias name

[Liping Zhang]

From: Liping Zhang <liping.zhang@spreadtrum.com>

Otherwise, if nfnetlink_log.ko is not loaded, we cannot add rules
to log packets to the userspace when we specify it with arp family,
such as:

  # nft add rule arp filter input log group 0
  <cmdline>:1:1-37: Error: Could not process rule: No such file or
  directory
  add rule arp filter input log group 0
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This qualifies as bugfix, so I'm applying this to nf. Thanks!
