net: mscc: ocelot: fix eMAC TX RMON stats for bucket 256-511 and above

Browse Source 
[ Upstream commit 52eda4641d041667fa059f4855c5f88dcebd8afe ]

There is a typo in the driver due to which we report incorrect TX RMON
counters for the 256-511 octet bucket and all the other buckets larger
than that.

Bug found with the selftest at
https://patchwork.kernel.org/project/netdevbpf/patch/20231211223346.2497157-9-tobias@waldekranz.com/
