tls: memory leak due to missing call to vnet_crypto_key_del
We add the crypto key to the vnet crypto library via vnet_crypto_key_add. However, when the session is disconnected, we don't call vnet_crypto_key_del and the memory is leaked in vnet_crypto library as well as in pico tls key store. It seems dispose crypto is the appropriate place to add vnet_crypto_key_del. Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: If6d1266baf686fefe5bb81330ce60b35c8ff574e
