After the rework, two files have a copy of drbd_nl_mcgrps[], but one
of them has no references:

drivers/block/drbd/drbd_nl_gen.c:641:42: error: 'drbd_nl_mcgrps' defined but not used [-Werror=unused-const-variable=]
641 | static const struct genl_multicast_group drbd_nl_mcgrps[] = {
| ^~~~~~~~~~~~~~

At the default warning level, -Wunused-const-variables is turned off,
so this has gone unnoticed.

Remove the extra variable.

Oops, looks like a copy/paste error on my side.
Thanks for noticing and fixing.
