check for the return status for eth_getenv_enetaddr_by_index() and eth_setenv_enetaddr() functions and print appropriate message on failure. Also convert debug message to printf().

Signed-off-by: Manjunath Hadli manjunath.hadli@ti.com Cc: Tom Rini trini@ti.com Cc: Mike Frysinger vapier@gentoo.org Cc: Wolfgang Denk wd@denx.de --- Changes for v2: Removed additional check of comparing ethernet address is all zeros, As the core code already calls is_valid_ether_addr() and one of the checks in there is for all zeros.
