Subject: crypto: chtls - remove redundant null pointer check before kfree_skb
Patch-mainline: v4.20-rc1
Git-commit: ce1294d981c1467c13b2b698913f35859592308b
References: bsc#1104270 FATE#325931

kfree_skb has taken the null pointer into account. hence it is safe
to remove the redundant null pointer check before kfree_skb.
