net: socionext: Fix a signedness bug in ave_probe()
[ Upstream commit 7f9e88e6ef8c971f2c638b5ff7044c59b5d0f58d ]
The "phy_mode" variable is an enum and in this context GCC treats it as
an unsigned int so the error handling is never triggered.
Fixes: 4c270b55a5af ("net: ethernet: socionext: add AVE ethernet driver")
