[GAMEPLAY] Galio's W can be interrupted

When fighting Yasuo, Galio's W skill (Shield of Durand) can be interrupted by Yasuo's knockup on the third cast of his Q. It says specifically in italics here, that_" Shield of Durand cannot be interrupted by crowd control"_. This is rather serious for Galio as his W provides anywhere between 20-40% baseline damage reduction plus 8% per 100 magic resist, which is rather huge for a tank to have when they are getting hit by a carry.

To reproduce: have one person play Galio and one play Yasuo, begin Galio's W channel then have Yasuo cast a 3rd cast of his Q.
