of: mdio: Fix a signedness bug in of_phy_get_and_connect()

[ Upstream commit d7eb651212fdbafa82d485d8e76095ac3b14c193 ]

The "iface" variable is an enum and in this context GCC treats it as
an unsigned int so the error handling is never triggered.

Fixes: b78624125304 ("of_mdio: Abstract a general interface for phy connect")
