Subject: [PATCH 1/9] pkcs11: Unbreak detection of unenrolled cards

This was broken since 58b03b68, which tried to sanitize some states,
but caused C_GetTokenInfo returning CKR_TOKEN_NOT_RECOGNIZED instead
of empty token information.

Note, that this has effect only if the configuration options
enable_default_driver and pkcs11_enable_InitToken are turned on.
Otherwise it still returns CKR_TOKEN_NOT_RECOGNIZED.
