pss: remove redundant verify_algorithm_id call in SigningKey::try_from

[VolodymyrBg]

The explicit [verify_algorithm_id()]

RSA/src/encoding.rs

Lines 152 to 169 in 1e94064

	/// Verify that the `AlgorithmIdentifier` for a key is correct.
	pub(crate) fn verify_algorithm_id(algorithm: &spki::AlgorithmIdentifierRef) -> spki::Result<()> {
	match algorithm.oid {
	pkcs1::ALGORITHM_OID => {
	if algorithm.parameters_any()? != pkcs8::der::asn1::Null.into() {
	return Err(spki::Error::KeyMalformed);
	}
	}
	ID_RSASSA_PSS => {
	if algorithm.parameters.is_some() {
	return Err(spki::Error::KeyMalformed);
	}
	}
	_ => return Err(spki::Error::OidUnknown { oid: algorithm.oid }),
	};
	Ok(())
	}

call before RsaPrivateKey::try_from() was redundant because RsaPrivateKey::try_from() already performs the same
check internally. This matches the pattern used in [BlindedSigningKey]

RSA/src/pss/blinded_signing_key.rs

Lines 31 to 38 in 1e94064

	pub struct BlindedSigningKey<D>
	where
	D: Digest,
	{
	inner: RsaPrivateKey,
	salt_len: usize,
	phantom: PhantomData<D>,
	}
