Verify the tag and finish the software AES-GCM decryption operation.

Parameters

[in,out]	operation	Pointer to the AEAD operation structure.
[out]	plaintext	Output buffer for remaining plaintext (typically none for CCM).
[in]	plaintext_size	Size of the plaintext buffer.
[out]	plaintext_length	Pointer to store the actual plaintext length.
[in]	tag	Authentication tag to verify.
[in]	tag_length	Length of the authentication tag.

Return values

PSA_SUCCESS	Authentication tag verified successfully.
PSA_ERROR_INVALID_SIGNATURE	Authentication tag verification failed.
PSA_ERROR_BAD_STATE	Operation not initialized.
