[v2] examples/ipsec-secgw: return on encountering algo as NULL

  if algo is NULL set the status to error and return. This change
prevent crashing of ipsec-secgw application when a specific
cipher/auth/aead algo are not supported by application.

Fixes: 0d547ed03717 ("examples/ipsec-secgw: support configuration file")
