etherdevice: introduce help function eth_zero_addr()

commit 6d57e9078e880a3dd232d579f42ac437a8f1ef7b upstream.

a lot of code has either the memset or an inefficient copy
from a static array that contains the all-zeros Ethernet address.
Introduce help function eth_zero_addr() to fill an address with
all zeros, making the code clearer and allowing us to get rid of
some constant arrays.
