Fix Melee Crit Damage

[ghollies]

• Recent fixes ended up calculating the crit damage based on AttackData.damage which need to be set on the object ahead of the calculation, other wise it asks of min/min range of 0-0

Oops. I meant to change CalculateMeleeCriticalDamage to take the damage amount (and return the critical amount) instead of working on the attack data directly, since having it being initialized from various places can easily create issues like this one, but apparently I forgot to change the arguments. Thanks.
