If register_netdev() fails, the error handling path of the probe will not
free the memory allocated by the previous airoha_metadata_dst_alloc() call
because port->dev->reg_state will not be NETREG_REGISTERED.

So, an explicit airoha_metadata_dst_free() call is needed in this case to
avoid a memory leak.

Sorry, I was a little too hasty.

This patch looks good to me, but as this is a fix for change
present in net it should be targeted at net.

  Subject: [PATCH v4 net] ...

And it should be split out from the patchset comprising the remaining
patches in this series, which appear to be clean-ups (or at least not
but fixes). This rump patch-set should be targeted at net-next.
And ideally, IMHO, have a cover letter.

  Subject: [PATCH v4 net-next 0/3] ...

Thanks!
