bhyveConnectDomainXMLToNative: Fix memory leak in incorrect virCommandToString usage

Browse Source 
virCommandToString returns an allocated buffer, so using it directly as
argument of virBufferAdd which doesn't consume the string causes it to
be leaked. Switch to virBufferToStringBuf since we are already using a
buffer.
