net: usb: asix: ax88772: Fix less than zero comparison of a u16 

The comparison of the u16 priv->phy_addr < 0 is always false because
phy_addr is unsigned. Fix this by assigning the return from the call
to function asix_read_phy_addr to int ret and using this for the
less than zero error check comparison.

Fixes: 7e88b11a86 ("net: usb: asix: refactor asix_read_phy_addr() and handle errors on return")
Addresses-Coverity: ("Unsigned compared against 0")
