sh_eth: check sh_eth_cpu_data::no_xdfar when dumping registers
When adding the sh_eth_cpu_data::no_xdfar flag I forgot to add the flag
check to __sh_eth_get_regs(), causing the non-existing RDFAR/TDFAR to be
considered for dumping on the R-Car gen1/2 SoCs (the register offset check
has the final say here)...
