[PATCH net-next v2 1/5] sh_eth: check sh_eth_cpu_data::no_tx_cntrs when dumping registers

[Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>]

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)...
