Subject: [rfc] b43: possible missing break in b43_wa_all

I'm going through all the 'missing break in switch' bugs in coverity, and
most of them look like intentional/false positives, but this one looks odd to me.

It seems the intent is to B43_WARN_ON only if we don't know the phy, so it seems
strange to do it after we've just initialized type 7.

If this is agreed to be a bug, I'll submit the below patch properly,
but I want to be sure this isn't something like "type 7 is work in progress"
It's been this way since 2007 though. I guess no-one runs with CONFIG_B43_DEBUG on.
