Jakub Kicinski b6c65eb20f tools: ynl: fix handling of multiple mcast groups
We never increment the group number iterator, so all groups
get recorded into index 0 of the mcast_groups[] array.

As a result YNL can only handle using the last group.
For example using the "netdev" sample on kernel with
page pool commands results in:

  $ ./samples/netdev
  YNL: Multicast group 'mgmt' not found

Most families have only one multicast group, so this hasn't
been noticed. Plus perhaps developers usually test the last
group which would have worked.
