HTTP parser: fixed memory overflow in the collisions test.
The level hash uses the NULL value as the indicator of a free entry in a bucket.
So, inserting a NULL value breaks the hash and can lead to a bucket overflow.
In case of the collision counter, the value wasn't initialized, since it's not
needed for the purpose of checking collisions. As a result, it might contain
any garbage from the stack and in some rare cases the value was NULL.
Now the value is initilized.
