hw/net/lan9118: Replace magic '2048' value by MIL_TXFIFO_SIZE definition

The magic 2048 is explained in the LAN9211 datasheet (DS00002414A)
in chapter 1.4, "10/100 Ethernet MAC":

  The MAC Interface Layer (MIL), within the MAC, contains a
  2K Byte transmit and a 128 Byte receive FIFO which is separate
  from the TX and RX FIFOs. [...]

Note, the use of the constant in lan9118_receive() reveals that
our implementation is using the same buffer for both tx and rx.
