net: ethernet: adi: Fix return value check in adin1110_probe_netdevs()
In case of error, the function get_phy_device() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().
Fixes: bc93e19d088b ("net: ethernet: adi: Add ADIN1110 support")
