[efi] Use casts rather than virt_to_bus() for UNDI buffer addresses

Browse Source 
For a software UNDI, the addresses in PXE_CPB_TRANSMIT.FrameAddr and
PXE_CPB_RECEIVE.BufferAddr are host addresses, not bus addresses.

Remove the spurious (and no-op) use of virt_to_bus() and replace with
a cast via intptr_t.
