[PATCH net-next] nfp: flower: remove unused index from nfp_fl_pedit()

[Pablo Neira Ayuso <pablo@netfilter.org>]

Static checker warning complains on uninitialized variable:

        drivers/net/ethernet/netronome/nfp/flower/action.c:618 nfp_fl_pedit()
        error: uninitialized symbol 'idx'.

Which is actually never used from the functions that take it as
parameter. Remove it.

Fixes: 738678817573 ("drivers: net: use flow action infrastructure")
