net: stmmac: use dev_err_probe() for reporting mdio bus registration failure
I have a board where these two lines are always printed during boot:
imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus
imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed
It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.
Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.
While here, add the missing \n to one of the format strings.
