[dpdk-dev] [PATCH] librte_sched: fix compile error on unused parameter red

[Jasvinder Singh <jasvinder.singh@intel.com>]

This commit fixes the following compile error messages when
CONFIG_RTE_SCHED_RED=n and CONFIG_RTE_SCHED_COLLECT_STATS=y;

rte_sched.c: In function ‘rte_sched_port_update_subport_stats_on_drop’:
rte_sched.c:1090:41: error: unused parameter ‘red’ [-Werror=unused-parameter]
		struct rte_mbuf *pkt, uint32_t red)
                                         ^
rte_sched.c: In function ‘rte_sched_port_update_queue_stats_on_drop’:
rte_sched.c:1116:39: error: unused parameter ‘red’ [-Werror=unused-parameter]
		struct rte_mbuf *pkt, uint32_t red)

Fixes: 4d51afb5cdb6 ("sched: keep track of RED drops")
