nvmem: layouts: u-boot-env: check earlier for ethaddr length

Browse source

Unfortunately the ethaddr value in U-Boot environment might be enclosed
in single/double quotes or be something completely different. This can
make it different than MAC_ADDR_STR_LEN, which results in EINVAL
returned by ethaddr post process. Move the check for length earlier,
to skip post processing, so nvmem could still present ethaddr value as
a string if the value doesn't match MAC_ADDR_STR_LEN.
