MdeModulePkg: Do not use hard coded TTL/ToS in PXE driver. 

EFI_PXE_BASE_CODE_PROTOCOL has interface to set the TTL and ToS value, but
not used by the UdpWrite() interface. The code always use a hard coded 16
for the TTL and 0 for ToS.
This patch update the UpdWrite() to use the TTL and ToS which have been set
by the SetParameters().
