[U-Boot] [PATCH] [PATCH] net/eth.c: Avoid Warning when ethxaddr is not set

[Gwenhael Goavec-Merou]

The return value for eth_getenv_enetaddr_by_index produces 
a Warning when ethXaddr is not set (env_enetaddr is equal 
to 00:00:00:00:00:00).

The validity of the mac address is tested later in this 
function to avoid to write an erroneous address.

The test of the function's return is consequently useless 
and adds a warning.
