Memory leak fix

[momchilmg]

file : src/crypto/slow-hash.c

line 479 : VirtualFree(hp_state, MEMORY, MEM_RELEASE);

The correct expression is : VirtualFree(hp_state, 0, MEM_RELEASE);

I have 24GB RAM and this wallet get 95% without this fix.

"If you specify this value, dwSize must be 0 (zero), and lpAddress must point to the base address returned by the VirtualAlloc function when the region is reserved. The function fails if either of these conditions is not met."

Thanks! :)

Confirmed.

Incorrect Size parameter for VirtualFree (MEM_RELEASE) operation.
200000 - Incorrect size used by the application.
0 - Expected correct size (0).

Need to check memory usage more.

Yes, but this is very hard work ;) For now I think this is enough.
