Clarify the use of MBEDTLS_ERR_PK_SIG_LEN_MISMATCH
...
Clarify what MBEDTLS_ERR_ECP_SIG_LEN_MISMATCH and
MBEDTLS_ERR_PK_SIG_LEN_MISMATCH mean. Add comments to highlight that
this indicates that a valid signature is present, unlike other error
codes. See

Fix theoretical compliance issue in ECDSA
...
The issue would happen for curves whose bitlength is not a multiple of eight
(the only case is NIST P-521) with hashes that are longer than the bitlength
of the curve: since the wides hash is 512 bits long, this can't happen.
Fixing however as a matter of principle and readability.
