While doing insert/remove (quickly) tests on USB, I managed to trigger

This patch prevents this oops.
There is still the larger problem of the overall race
that caused this in the first place, but much of the rest
of the code in class.c appears to also do NULL checks to
avoid Oops'ing, so this continues the tradition.

As this is a bandage over the real problem, I'd prefer to not apply this
one right now until we find the root cause.

Ahh.. but the problem there, is that you've already said you will
not be looking for any cause. This patch prevents the Oops,
in the same manner as existing code in that same file.
Would you perhaps prefer a second patch to remove all of the other
existing bandages from that file? I don't think so.
This patch fixes a *real* ooops that can occur on servers, desktops,
and portables whenever a USB device is connected.
Sounds like something worth fixing.
Cheers
