[PATCH net v2] net: phy: fix a return path in get_phy_c45_ids()

[Charles Perry <charles.perry@microchip.com>]

The return value of phy_c45_probe_present() is stored in "ret", not
"phy_reg", fix this. "phy_reg" always has a positive value if we reach
this return path (since it would have returned earlier otherwise), which
means that the original goal of the patch of not considering -ENODEV
fatal wasn't achieved.

Fixes: 17b447539408 ("net: phy: c45 scanning: Don't consider -ENODEV fatal")
