* When build a DHCP message in function DhcpSendMessage() or DhcpRetransmit(), a new NET_BUF is created by the library of NetbufFromExt, but it's not freed after it is sent out. This patch is to fix this memory leak issue. V2: * Since packet has already been referred by DhcpSb->LastPacket, and will be freed when sending another packet or clean up, there is no need to add an extra free function in NetbufFromExt.
