Title: buffer: fix regression in buffer.slice

4c9b30d introduced a change that explicitely initializes buffer.parent
to null. However, buffer.slice explicitely tests if buffer.parent is
strictly equal to undefined to determine how to set the parent of the
newly created buffer. This change fixes this inconsistency that
introduced a regression in buffer.slice for buffers larger than
Buffer.poolSize.
