f2a622975a litex_sim/xgmii_ethernet: fix RX frame check sequence generation 
The rewritten XGMII Ethernet module generates proper frame check
sequences (FCS) on Ethernet frames received by the simulation, such
that the unmodified MAC pipeline including CRC checking can be
used. However, the byte order of the generated frame check sequence
has been inverted. This becomes apparent when one specifies that the
CRC should be calculated in the LiteX BIOS.

This fixes the byte order to be correct. The similar GMII Ethernet
module did not contain this mistake.

Fixes: 7b533a032d ("litex_sim: rewrite XGMII verilator...")
