Subject: chtls: Replace skb_dequeue with skb_peek
Patch-mainline: v5.11-rc3
Git-commit: a84b2c0d5fa23da6d6c8c0d5f5c93184a2744d3e
References: bsc#1104270 FATE#325931

The skb is unlinked twice, one in __skb_dequeue in function
chtls_reset_synq() and another in cleanup_syn_rcv_conn().
So in this patch using skb_peek() instead of __skb_dequeue(),
so that unlink will be handled only in cleanup_syn_rcv_conn().

Fixes: cc35c88ae4db ("crypto : chtls - CPL handler definition")
