net: bgmac: Fix return value check for fixed_phy_register()
[ Upstream commit 23a14488ea5882dea5851b65c9fce2127ee8fcad ]
The fixed_phy_register() function returns error pointers and never
returns NULL. Update the checks accordingly.
Fixes: c25b23b8a387 ("bgmac: register fixed PHY for ARM BCM470X / BCM5301X chipsets")
