errors when is requested engine information

[petrovr]

OpenSSL engine command support some flags that could be used to obtain information for specified engines(all if not).
Unfortunately ibmpkcs11 engines print a lot of errors.

Tested command : openssl engine -vvvv
Openssl configuration:

openssl_conf = openssl_def

[openssl_def]
engines = engine_section

[engine_section]
engine1 = ibmpkcs11_section

[ibmpkcs11_section]
dynamic_path = ..../src/.libs/ibmpkcs11.so

So as engine is not in use yet all those checks could be postponed, right?

Another case is command: openssl engine -t{t}
Engine is not reported as available. Perhaps is related to above errors.

Engine initialization may be is not correct place.
Looking into e_nns actually check for missing arguments (configuration) is performed late - when is requested load of key or certificate.
As e_nss supports OpenSSL STORE2 API configuration is checked when store is opened.
With other words check is performed just "before use".
