sh_eth: check sh_eth_cpu_data::cexcr when dumping registers
When adding the sh_eth_cpu_data::cexcr flag I forgot to add the flag
check to __sh_eth_get_regs(), causing the non-existing RX packet counter
registers to be considered for dumping on the R7S72100 SoC (the register
offset sanity check has the final say here)...
