[ Upstream commit 6eaeedc1aa27a423bd89043705eca39215015bb3 ]
When adding the sh_eth_cpu_data::no_tx_cntrs flag I forgot to add the flag check to __sh_eth_get_regs(), causing the non-existing TX counter registers to be considered for dumping on the R7S72100 SoC (the register offset sanity check has the final say here)...
