Update cases for C_GetAttributeValue

[microshine]

For each (type, pValue, ulValueLen) triple in the template, C_GetAttributeValue performs the following algorithm:

• If the specified attribute (i.e., the attribute specified by the type field) for the object cannot be revealed because the object is sensitive or unextractable, then the ulValueLen field in that triple is modified to hold the value -1 (i.e., when it is cast to a CK_LONG, it holds -1).
• Otherwise, if the specified attribute for the object is invalid (the object does not possess such an attribute), then the ulValueLen field in that triple is modified to hold the value -1.
• Otherwise, if the pValue field has the value NULL_PTR, then the ulValueLen field is modified to hold the exact length of the specified attribute for the object.
• Otherwise, if the length specified in ulValueLen is large enough to hold the value of the specified attribute for the object, then that attribute is copied into the buffer located at pValue, and the ulValueLen field is modified to hold the exact length of the attribute.
• Otherwise, the ulValueLen field is modified to hold the value -1.
