John Fastabend 715f378f42 bpf, sockmap: Fix potential memory leak on unlikely error case 
[ Upstream commit 7e6b27a69167f97c56b5437871d29e9722c3e470 ]

If skb_linearize is needed and fails we could leak a msg on the error
handling. To fix ensure we kfree the msg block before returning error.
Found during code review.

Fixes: 4363023d26 ("bpf, sockmap: Avoid failures from skb_to_sgvec when skb has frag_list")
