[Root Cause Analysis]
The PXE offer selection in the PXE driver is splitted into two passes and the two passes are required to follow the same flow. However, in current code, there is some difference between the two.
[Solution]
make the second offer selection pass exactly match the first one.
2. Fixed one bug when allocating pool for UDP transmit packet.

Problem with PXE boot to Windows Server 2008 install. The reason is that UdpRead and UdpWrite interfaces cannot work well with the same UDP instance.
[Solution]
Use separate instances for UDP Read and UDP write in UefiPxeBC module.
[Impaction]:
UefiPxeBcDxe and Udp4Dxe module.
