Jian Zhang b70c4e5e71 net: ncsi: fix skb leak in error paths 
commit 5c3398a542 upstream.

Early return paths in NCSI RX and AEN handlers fail to release
the received skb, resulting in a memory leak.

Specifically, ncsi_aen_handler() returns on invalid AEN packets
without consuming the skb. Similarly, ncsi_rcv_rsp() exits early
when failing to resolve the NCSI device, response handler, or
request, leaving the skb unfreed.

Fixes: 138635cc27 ("net/ncsi: NCSI response packet handler")
