net: use dev_warn() when no MAC address is set

When a SoC such as VF610 has no addresses programmed for both its
interfaces, the "No MAC address set" warning can be confusing:

    booting 'net'
    WARNING: net: warning: No MAC address set. Using random address a2:e8:be:79:72:01
    WARNING: net: warning: No MAC address set. Using random address aa:d5:d7:10:c0:42

This patch uses dev_warn() instead and removes the redundant "warning":

    booting 'net'
    WARNING: eth0: No MAC address set. Using random address a2:e8:be:79:72:01
    WARNING: eth1: No MAC address set. Using random address 4e:be:c4:bc:ce:36
