Description:
------------
mysqli_query function does not fail with a warning message when invalid queries are sent.

Reproduce code:
---------------
error_reporting(E_ALL);
$link = mysqli_connect("localhost", "andrei.tudor", "babardeala", "test");
$result = mysqli_query($link, "SELECT * FROM Groupss");

Expected result:
----------------
I use that query but in my database there is no table called "Groupss". So there should be a warning message shown on my screen even if i don't call mysqli_error() function.

Actual result:
--------------
There is no warning message.
This happens for any wrong query string.
