[U-Boot] [PATCH] net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall back

[Eric Miao]

Ignore the return value of eth_getenv_enetaddr_by_index(), and if it
fails, fall back to use dev->enetaddr, which could be filled up by
the ethernet device driver.

Actually, this is the original behavior, and was later changed by
commit 48506a2cde2458fa1f8c5993afc98e5a4617e1d3.
