net/tls: Removed redundant checks for non-NULL
Removed checks against non-NULL before calling kfree_skb() and crypto_free_aead(). These functions are safe to be called with NULL as an argument. Signed-off-by: Vakul Garg <vakul.garg@nxp.com> Acked-by: Dave Watson <davejwatson@fb.com> Signed-off-by: David S. Miller <davem@davemloft.net>
