Staging: Convert uses of compare_ether_addr to ether_addr_equal

Preliminary to removing compare_ether_addr altogether:

Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.

Additionally:

Used is_zero_ether_addr, removed now unused variable
Converted uses of &foo[0] to foo

Done via cocci script: (and a little typing)

$ cat compare_ether_addr.cocci
