Subject: [PATCH] tpm2: Return TPM_RC_VALUE upon decryption failure
When decryption fails then return TPM_RC_VALUE rather than TPM_RC_FAILURE.
The old error code could indicate to an application or driver that
something is wrong with the TPM (has possibly gone into failure mode) even
though only the decryption failed, possibly due to a wrong key.
