RGMII issue with Jetpack 5.1.1 (KSZ9131)

FYI–

This is still an issue in Jetpack 5.1.2, apparently. I’m not using macsec. My approach is to add this after the devm_kfree() at the init-err label:

pdata->macsec_pdata = NULL;

Thanks for digging into things @haensler! Your info made for a very quick fix.
