net: dm: check the boundary of skb drop reasons
The 'reason' will be set to 'SKB_DROP_REASON_NOT_SPECIFIED' if it not
small that SKB_DROP_REASON_MAX in net_dm_packet_trace_kfree_skb_hit(),
but it can't avoid it to be 0, which is invalid and can cause NULL
pointer in drop_reasons.
Therefore, reset it to SKB_DROP_REASON_NOT_SPECIFIED when 'reason <= 0'.
