$.inArray crushes IE6 and Chrome if second argument is `null` or `undefined`

[Anton Ryzhov]

$.inArray crushes IE6 and Chrome if second argument is null or undefined, but in Firefox and Opera native functions returns -1.

Following patch unifies $.inArray behavior and avoids JS-engine from crush.

Test case is available ​here.

The real issue is that the correctly thrown TypeError is preventing the method from returning a value:

Uncaught TypeError: Array.prototype.indexOf called on null or undefined
