[PATCH] net: stmmac: dwmac-meson8b: Fix an error handling path in 'meson8b_dwmac_probe()'

[Christophe JAILLET]

If 'of_device_get_match_data()' fails, we need to release some resources as
done in the other error handling path of this function.

Fixes: efacb568c962 ("net: stmmac: dwmac-meson: extend phy mode setting")
