Fix syntax error in C_UnwrapKeyAuthenticated function declaration

[KaganCanSit]

Description

This PR fixes a syntax error in the C_UnwrapKeyAuthenticated function declaration in pkcs11f.h. The issue was a missing comma between the ulAssociatedDataLen parameter and the phKey parameter, which causes compilation failures.

Changes Made

• Added missing comma after CK_ULONG ulAssociatedDataLen parameter in the C_UnwrapKeyAuthenticated function declaration

Error Details

The missing comma caused the following compilation error:
error: expected ',' or '...' before 'CK_OBJECT_HANDLE_PTR'
1325 | CK_OBJECT_HANDLE_PTR phKey
| ^~~~~~~~~~~~~~~~~~~~

Testing

• Verified that the fix resolves the compilation error
• Tested with GCC 12.2.0 on Linux x86_64 (Debian)
• No functional changes, only syntax correction

This is a minor but critical fix that ensures the header files compile correctly across different compilers and platforms.
