net: Print error message upon net usage when no ethernet-interface is found

This patch fixes a problem seen on PPC4xx boards, when no MAC address is defined. Then no ethernet interface is available but a simple "tftp" command will return without any error message which is quite confusing. Signed-off-by: Stefan Roese <sr@denx.de>
