Bug description:RSA encryption fails without padding

Description:
------------
openssl_public_encrypt fails with the argument OPENSSL_NO_PADDING. Without
it, it works fine.

Test script:
---------------
$configargs = array
   ("private_key_bits" => 4096,
    "private_key_type" => OPENSSL_KEYTYPE_RSA,
    "encrypt_key" => false);
$key = openssl_pkey_new($configargs);
$details = openssl_pkey_get_details($pubkey);
$pubkey = $details['key'];
$r = openssl_public_encrypt("This is a test", $crypted, $pubkey,
OPENSSL_NO_PADDING);
if ($r) {
  echo "encrypt no padding: true\n";
} else {
  echo "encrypt no padding: false\n";
  $r = openssl_public_encrypt("This is a test", $crypted, $pubkey);
  if ($r) {
    echo "encrypt with padding: true\n";
  } else {
    echo "encrypt with padding: false\n";
  }
}

Expected result:
----------------
encrypt no padding: true

Actual result:
--------------
encrypt no padding: false
encrypt with padding: true
