[PATCH net-next] net: socionext: remove set but not used variable 'pkts'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ethernet/socionext/netsec.c: In function 'netsec_clean_tx_dring':
drivers/net/ethernet/socionext/netsec.c:637:15: warning:
 variable 'pkts' set but not used [-Wunused-but-set-variable]

It is not used since commit ba2b232108d3 ("net: netsec: add XDP support")
