With all defenses down and no luck of occasionally avoided hits, you're likely to get clubbed down in such a situation.
You cleared a 350k stagger that you received from the first melee hit Garrosh gave you after his whirl, while being at approximately full health. This was probably a waste of chi, but I don't think this is what killed you in the end.
Are you out of melee range of the boss while he whirls? The occurance of Spirit Link during the whirl either suggests that you all stack on the boss during the whirls, or that one tank stays behind while the rest is out of melee range. If you're out of melee range, chances are you won't have EB stacks ready when you need to tank the boss.
In my opinion the best way to deal with this is planning your EB/cooldowns a bit better; call for an external when you don't have any defenses up/left or planned for something else in the near future. Expel Harm could have been a lifesaver as well - don't be afraid to use it after taking a full hit to the face. You could also opt to get the four piece bonus or get a bit more mastery, but in the end, proper cooldown usage will trump a small shift in stats.
