Fix key size of PrivateRefCountHash.

Browse source 
The key is the first member of PrivateRefCountEntry, which has type
Buffer.  This commit changes the key size from sizeof(int32) to
sizeof(Buffer).  This appears to be an oversight in commit
4b4b680c3d, but it's of no consequence because Buffer has been a
signed 32-bit integer for a long time.
