scsi: 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.

Done via cocci script:

$ cat compare_ether_addr.cocci
