compat: backport ether_addr_equal

This backports:

    commit a599b0f54d233d0f63d6be9a2ff0049d24751669

        etherdevice.h: Add ether_addr_equal

        Add a boolean function to check if 2 ethernet addresses
        are the same.

        This is to avoid any confusion about compare_ether_addr
        returning an unsigned, and not being able to use the
        compare_ether_addr function for sorting ala memcmp.
