[net v2] sch_fq_codel: zero q->flows_cnt when fq_codel_init fails

When fq_codel_init fails, qdisc_create_dflt will cleanup by using qdisc_destroy. This function calls the ->reset() op prior to calling the ->destroy() op. Unfortunately, during the failure flow for sch_fq_codel, the ->flows parameter is not initialized, so the fq_codel_reset function will null poi
