IntelFrameworkModulePkg Snp16Dxe: Remove redundant functions

The redundant functions which are never called have been removed.
They are PxeUndiSetMcastAddr, PxeUndiInitiateDiags,PxeUndiGetState
PxeUndiForceInterrupt and PxeUndiSetPacketFilter.

-  Description: This call forces the network adapter to generate an interrupt. When a receive interrupt occurs, the

-  network adapter driver usually queues the packet and calls the application's callback receive

-  routine with a pointer to the packet received. Then, the callback routine either can copy the packet

-  to its buffer or can decide to delay the copy to a later time. If the packet is not immediately copied,

-  the network adapter driver does not remove it from the input queue. When the application wants to

-  copy the packet, it can call the PXENV_UNDI_FORCE_INTERRUPT routine to simulate the receive

-  interrupt.
