ethernet/netronome/nfp: Fix a use after free in nfp_bpf_ctrl_msg_rx
In nfp_bpf_ctrl_msg_rx, if
nfp_ccm_get_type(skb) == NFP_CCM_TYPE_BPF_BPF_EVENT is true, the skb
will be freed. But the skb is still used by nfp_ccm_rx(&bpf->ccm, skb).
My patch adds a return when the skb was freed.
Fixes: bcf0cafab44fd ("nfp: split out common control message handling code")
