RFR: 8353329: Small memory leak when create GrowableArray with initial size 0 [v2]

[Zhengyu Gu]

> Please review this small fix to avoid 1 byte leak when create a GrowableArray with initial size = 0.
> 
> GrowableArray's c-heap allocator does not check size = 0 and os:malloc(0) will malloc at least 1 byte.
